Chrysler: Problems & Solutions

Troubleshooting Chrysler Car Problems

Chrysler Concorde LXi

TRANSMISSION FLUID CHANGE 


PROBLEM:

Chryser 2004 Concorde Lxi started 

to 'slip' last week, when starting off from a traffic light. Also, I noticed a slight down-shift while in cruse control on the freeway when going up a small hill 

Transmission fluid changed 150,000 miles ago. Will I need to just have the fluid changed again? I presently have over 330,000 miles on the car.

SOLUTION:

Well the trans fluid should be replaced at 60 to 90K intervals, so you are WAY overdue for that service. So yes do a fluid and filter change. Now that may help, but if it does not, then you may need to get the transmission overhauled or replaced. 330,000 miles on a transmission is a lot, and the vehicle transmission is getting worn out. But do the service. You may be able to get another 50K out of her.

2001 Chrysler Concorde Fuel Filter

PROBLEM:
How many fuel filters  2001 Chrysler Concorde 2.7L has, where are they located and how often they should be changed?


SOLUTION:
2001 Chrysler Concorde vehicle does not have a fuel filter.Instead of fuel filter  it has a strainer which is built into the pump and is not replaceable.If the strainer is causing the problem,then you will have to replace the complete pump assembly. That will solve the problem.

Add ATF Fluid 

PROBLEM:

2008 Chrysler sebring convertible 2.4L trying to add some aft fluid to the top pump.

SOLUTION:

The pump motor IS under the spare tire area. Remove the spare tire cover and then the plastic trim panel at the rear of the trunk and you'll find the pump assembly near the trunk latch. The fill plug is on the pump assembly where you can fill it after the leak is repaired. 

PLEASE NOTE: This system does not use ATF, you'll need ARAL VITAMOL ZH-M fluid to top it off after a repair or a leak.


Chrysler Town & Country LX


Steering Column Switch Stuck Up

PROBLEM:

06 Town & Country LX Accel/Resume switch on the steering is stuck down in the "on" position. This is causing an inability to engage the cruise control.

SOLUTION:

Basic possibility for Switch to Stuck:

If the switch is stuck it is either because of a mechanical failure of the switch or something stuck in it. I'm assuming you've already made sure nothing is stuck in it that you can view from outside.

For Example: If a sticky liquid like soda or fruit juice was spilled on the switch that would have ran inside and gummed it up and would cause it to stick. One thing you can try, whether there was a spill or not, is try to spray some electrical contact cleaner inside the switch and see if it will free up. The cleaner will hopefully dissolve anything that could be causing it to stick, yet it won't cause further problems like water would.

But If Its Not Helping:
Aside from cleaner and physically trying to pry the switch with something like a small screwdriver, if you are unable to get it to move again then the switch will need to be replaced.May be its worn out and acting like this.


Chrysler Pacifica


Shift Stuck In Park

PROBLEM:

2005 Chrysler Pacifica and the shift is stuck in the park position. It will not shift out of park

SOLUTION:

There are few possibilities,that you will have to inspect and confirm first.

With key ON and your hand on the shifter, when you press the brake, can you feel or hear the interlock solenoid operating? Make sure a/c fan and radio is off to help hear the noise from the interlock solenoid.
(When pressing the brake with the key on can you hear or feel the interlock solenoid operating?).

Important Note: On some of these vehicles there is a "plug" covering a hole in the shifter bezel around the shift lever. The bezel also contains the path for the shifter to move. 
Please check if on your chrysler if there is a plug . If you see the plug then you should be able to remove the plug, stick something through the hole to touch a release tab on the shifter, and see if the shifter will move out of park that way. 

Mostly Possible Faults In Such Case:

Most likely you have a failure with the interlock solenoid, interlock cable, or an issue with the shifter itself. If your vehicle has the plug and interlock release tab you should be able to allow operation until you can get your issue resolved.

Things You Can Try:
You can attempt to disconnect the solenoid from the cable and see if it will allow operation. You will need to remove the trim panel below steering column that covers lower section of the dash. Then remove the steering column shrouds that are around the steering column behind the steering wheel. With this trim removed you can see the interlock cable attached to the back of the ignition switch.

If Disconnecting The Shift Cable Is Not Helping:
 If you disconnect the wiring to the cable it should release the interlock solenoid and allow the shifter to be moved. If it still doesn't shift out of park there is a problem with the shifter assembly itself.

See Below The Diagram Showing 
Interlock cable removed from back of ignition switch

Chrysler Jeep Liberty/Cherokee


EGR Control Valve Problem

PROBLEM:
List of Problems Noticed On Chrysler Jeep:
Chrysler liberty/cherokee 2.8 automatic diesel. 
  • It idles a little roughly,
  • When brake is applied the rev counter goes to 700 RPM and then back to the normal 750 RPM 
  • It has stalling problem.
  • Yesterday it lost all power after a corner, no acceleration (Turned it off, on again and fine??).
  • It emits black smoke. 
  • The catalytic converter is quite blocked.

SOLUTION:

First of all confirm if there is check engine light coming up ON dash.If yes scan for codes.The error codes will point out what is issue.


If there is no check engine light coming on, then all problem is indicating towards EGR flow control valve.
This valve may be sticking closed at times especially when coming to a stop. I have replaced this valve (which is like a throttle body) for issues like this.Also a faulty EGR will cause black smoke problems.
Go Through 

AUTOMOTIVE EMISSIONS?


Inspect EGR Valve:
I recommend having the EGR flow control valve checked and or replaced. Sometimes just cleaning the soot from it will help. Like I mentioned, it looks like a throttle valve and i's the device that the intake hose from the intercooler connects to. 

Other Possibility Can Be Vacuum Problem:

Yes inspect all of the vacuum lines from the little vacuum pump and the solenoids to the turbocharger waste gate actuator and repair any loose or cracked hoses. 
Why its rare for vacuum issue because ,Usually though when there is a vacuum problem, a check engine light will come on and set a under boost code. But still dont ignore Vaccum Leak Issue.Also check all of the air intake hoses at the intercooler, turbo, and at the EGR flow control valve.


Chrysler Town & Country


Engine Overheats

PROBLEM:

2004 Chrysler T&C, 3.3L 

engine overheats after driving only  few miles. Already replaced the radiator, the water pump, and the thermostat.


SOLUTION:

There are few possibilities for engine overheat while driving.
The first place I would start with this is with the cooling fans. Make sure they are coming on when the engine gets hot.You can also turn on the a/c and this should activate the fans.If the fans are not coming ON,then its issue with fan.For that fan motor and fan control relay has to be checked.

But If Fans Come ON and still it overheats
Then inspect does the check engine light come on or the engine run rough?

If its running rough,then inspect the spark plug and ignition cylinder.

Combustion Test:
 Also it's possible that there is a small head gasket leak on any cylinder. The next step should be a combustion test kit to see if combustion gases are coming into the cooling system and causing the over heat.
Also make sure the system is bled properly, 
The radiator is  replaced but if the radiator lines are not bleed properly it can cause such the problem.


If it is a small leak on the cylinder,the best repair will be to replace the head gasket. If the exhaust is getting into the coolant you can't really use any of the sealers to solve the problem.The gasket replacement is the only option.The Haynes manual for your vehicle  should provide details in how to replace it for you. But please make sure do the leak check first however.


Chrysler Sebring

Chrysler Error Code P1598

A/C Not working and Error code P1598 present.The Problem noticed on 2003 Chrysler Grand Caravan.

Troubleshooting from Free car repair guide.
ARE THIS BOTH PROBLEMS INTER RELATED?

Yes,they are.A/C not working and error code P1598 are related to each other.
The error code is pointing towards the faulty part,that needs to be inspected to make your Air-conditioner work as before.

OK,WHAT PART IS THE ERROR CODE INDICATING TO CHECK?


OBD Error code P1598 indicates problem with a/c pressure transducer.

OK,GOOD GIVE ME MORE DETAIL ABOUT THIS?

Yes sure,the a/c pressure transducer is a pressure sensor on an a/c line. The transducer tells the power train control module(PCM) the actual pressure in the high side of the a/c system. The Error code P1598 is telling you to inspect,test the A/c pressure transducer.

OK,WHERE IT IS LOCATED AND WHY THE A/C COMPRESSOR IS NOT ENGAGED?


To locate this part,See behind the air filter box , mounted to the right strut tower you will find the receiver/drier. There is a small line leaving the top of the drier that goes back to the firewall.
Now on this line you will see a pressure sensor screwed on.
This has a three wire gray color electrical connector. This is the transducer.
Without it's proper signal the a/c compressor isn't going to engage.And that is why in your case too,the compressor is not getting engaged.So its very clear indication to get the Transducer checked and replace if faulty.

CAN I TEST THE TRANSDUCER BEFORE REPLACING IT?
YES Definitely,you can test it.before replacing the part.The testing will give you exact confirmation,that you are replacing the part which is actually faulty.

THAT'S GOOD,GIVE ME THE PROCEDURE?

To test this part you will require digital voltmeter.Now follow this process, unplug the transducer and turn the key on. See if there are two wires with 5v and ground on the third. If all three are ok then the wiring is good, replace the transducer.

If you don't have a voltmeter to do the testing then I would recommend replacing the transducer.Because as per the OBD error code and your problem description,its pointing towards faulty Transducer.

This details will help.
Thanks.

Car AC Blows Warm Air ?

There are many possibilities for Car AC blowing warm Air.
This problem is very common and noticed by Many cars and Truck users.

The possibilities for this problem are:---
1) Refrigerant is getting lost on AC system.
2) Compressor not engaging when  A/C is turned ON.
3) There is obstruction / clog in the system.
4) The blend air door  is stuck inside the HVAC unit.


The Blend door getting stuck problem is very much noticed.The blend door actually moves as per you set for heat and cold.If the blend door is stuck up in HEAT mode,then no air will pass through evaporator and warm air will blow.




For troubleshooting the problem in your case.You have to check all the possibilities mentioned.


You can start by inspecting the function/ working of compressor.


Is the compressor engaging when you turn ON the AC in your car.


If you notice that compressor is engaging, this confirms that AC is working properly.This also confirms that there is enough refrigerant in your system.So if compressor is working,then the problem is towards blend door motor.The Blend door motor needs to be replaced.Its located in the HVAC unit.The HVAC unit has to be taken out,to replace blend door controlling motor.
This is not a easy job.Its time consuming job.


BUT,NOW think on the other side.If your compressor is not working.
When you turn ON AC,the compressor is not engaging,then.
In that case there are two possibilities.
1) The compressor itself is faulty.
2) The problem is related to AC clutch.
To confirm this you will have to do a simple jump wire test.


In this test you connect compressor clutch wire directly to the battery.Please use fused jumper wire,so if fuse blows,then you know that clutch is problem.
Now if the compressor runs while you jump compressor clutch wire,then its confirmed that compressor is running and working.And the problem is with clutch related components.The clutch related components are bad A/C compressor clutch relay or a bad clutch cycling switch or pressure switch.


But if compressor is  running when you jump the compressor clutch ,but compressor is not engaging,then problem is with compressor clutch.


If the compressor clutch engages and compressor starts running but still you get no cold air then its problem of refrigerant.Its low or getting leaked.AC pressure test needs to be done.




TO CHECK REFRIGERANT :---


You will have to get AC pressure gauge testes,to check refrigerant in the system.
Connect the pressure gauge tester to the high port of the AC.
There are to ports,high port and low port.The high pressure port is located between the compressor and the condenser in the front of the engine compartment.If the pressure is checked low then,AC compressor will not engage.Because low pressure safety switch  will not trip to engage the compressor.If the refrigerant is checked low, then AC refrigerant has to be recharged.The air in the system has to be purged out,before filling/charging AC system with refrigerant.The refrigerant should not be overfilled or under-filled.If you dont know exact refrigerant capacity of refrigerant required in your car AC system,then get detail from cars manual or from local car AC repair service store or from local HVAC technician.


To do refrigerant pressure test,the procedure is as follows:---
Click the link below:---
http://howtobyme.blogspot.com/2011/10/how-to-test-auto-ac-pressure.html


But if the refrigerant is checked ok and compression is also running properly,and still the AC is not cooling and just blowing warm air,then its blockage issue.


The dirt clog obstructed in the orifice tube.The orifice tube is located in the high pressure hose between the condenser in the front of the radiator, and the evaporator located in the passenger compartment.Due to the clog in orifice tube, the refrigerant will not pass freely in the system.In that case the orifice tube needs to be cleaned,serviced.


If you see frost or condensation on the high pressure line from the condenser to the evaporator and AC is blowing warm air.You get no cool air from any vents, then problem is blend door .The door is stuck in the HEAT position, or possibly a badly clogged cabin air filter that is restricting airflow.You will have to manually take apart the dash and inspect the movement of blend door and see.If you notice that door moves freely and its not stuck,then problem is climate control module.






This procedure should help.
