Climate control will not turn OFF

Buick LeSabre Climate control will not turn OFF

When the blower motor will not shut off, even with the ignition off and/or only works on the highest setting, this is most commonly a sign of a faulty Blower Motor Control Module. It's located under the hood, towards the rear of the engine compartment, mounted to the blower motor housing (see image below). Inspect the wire harness and electrical connector for any loose, broken, melted or damaged wires. If the visual inspection checks ok, suspect a faulty Module.




Other possibility can be faulty relay:---

If the relay is your problem with the fan staying on it is located here:



The two on the right are the cooling fan relays

The wiring diagram the fan motors is below





For the manual system pull the blower motor relay and see if that turns the fan off. If it does replace that one. The relay is about $13 list but it will be less at a parts store.

If you have levers it is manual if you have a display you set to a temperature and the system keeps that temp it is automatic.

Here is the correct diagram for a manual system

There is a relay on your system that will shut off the blower but that is not the problem. The component that failed is the blower power module which is located here next to the blower motor on the firewall:

It is $124 at Advance auto parts


This is the speed controller for the blower motor. First check the 10A red fuse (#11) in the underdash relay panel on the passenger side for the blower motor that is located here.

If fuse 11 is good or if you replace it and the fan continues to malfunction you will have to replace the blower power module.

This details will help.

Thanks.

Fig. Blower motor and fan assembly removal

1. Unfasten the blower motor mounting screws, then remove the blower motor from the vehicle.
2. If the blower motor fan (also called a 'squirrel cage') must be replaced, use the following procedure:

NOTE

Do not hammer on the motor to remove or install the fan. Do not apply force to the motor housing to seat the fan on the motor, or motor/shaft bearing damage could result. Do not apply pressure to the fan rim. Be sure the correct replacement part is used.

1. Remove the metal star clip retaining the fan cage to the motor shaft.
2. Remove the fan by pulling straight out.

To install:

1. If removed, install the blower motor fan, as follows:
   1. Install the replacement fan cage onto the motor shaft.
   2. Adjust the fan cage to get a clearance of 0.30 inch (7.5mm) to the motor mount plate.
2. Install the remaining components in the reverse of the removal procedure. Make sure the electrical connection is secure. Tighten the motor screws to 14 ft. lbs. (20 Nm).
