2006 Ford F150: Will Not Shift out Of Park?

The Vehicle not shifting to drive or reverse mode.
The Gear shifter stuck in park mode.

When the shifter will not shift from Park,

First- Check your rear brake lights to see if they are working when you step on the brake pedal.
If the brake lights are NOT working, check your fuses.
If the fuses are good, and still no brake lights, then the problem will be the Stop Lamp Switch.

The Stop Lamp switch is located at the top of the brake pedal arm.

Working of Stop Lamp switch:----
This switch controls the rear brake lights, and also sends a signal to the Shift Interlock, telling it to release when the brake pedal is depressed.

Carefully inspect the electrical connector for any loose, broken or damaged wires. If the visual inspection checks ok, replacing the switch will solve the problem.

See this help diagrams shown below for exact part location:-----

NOW think other way.

If the brake lights ARE working, then the problem is going to be in the Shift Interlock system. Most commonly, the Interlock Solenoid. The interlock solenois is located on the steering column, behind the steering wheel and clockspring assembly. Again, inspect the electrical connector for any damaged or loose wires. If the visual inspection checks ok, suspect a faulty Interlock Solenoid.

See the diagram showing the shift interlock solenoid

In this types of problems there aren't many other items involved in the Interlock System. It's the brake light switch, to the shift interlock solenoid, which releases the lock on the shift cable. Ford does not provide an "over-ride" procedure, however, on "SOME" models, turning the key to "ACC" and then shifting to Neutral does the trick. Also, sometimes, the shifter is just "hard" to shift from park due to an incline. Try to have someone push the vehcile a bit, and relieve some pressure on the rear wheels, and then try to shift. BUT If the Interlock solenoid is the culprit, then, it is what has to be replaced.

This details will help.
Thanks.

Ignition locked up on Mercury Villager?

Many car users notice this types of problem.
After the car is parked,the Ignition will not get unlocked.Very frustrating issue.Because all was going well and sudden;ly without any reason,the ignition gets locked.

Basically in such cases,the
Key will not the ignition to start position.

So first try to slightly wiggle the vehicle front and back.Also try to turn the steering wheel left to right and right to left.In some cases this helps,but if its not helping this time,then
See if the vehicle is parked on a slope road,then its quite possible that gears are getting locked due to that pressure and this is causing the problem.
The car should always be parked on flat surface,instead of incline or decline road surface.

If in your case you are parked on a incline it may very well be just binding from the downward slope. I would try blocking the rear wheels and try jacking the front end up enough to get the tires off the ground and if its bound up it will likely release.
In some cases this helps.But if in your case,its not helping then you very likey have a bad ignition switch and replacement would be required.

See the details to perform this task is as follows :-----

Enclosed are the replacement instructions. The steering wheel will need to come of as well.
