Buick Rainier Problems

Air Conditioning only blows out the bottom ventts

I had a new battery installed and since the air condition only blows out on my feet. I have heard that this is has been an issue with several owners. Have you run across this and any ideas how to fix it? (Fuses have been checked, and the battery has been disconnected and reinstalled)

Driver's Door Window Switch Shorts And Catches Fire

The driver's door power window switch module may get contaminated with liquids causing a fire hazard. Dealers will replace the driver's door switch module free of charge to resolve the concern.

Headlights & Daytime Running Lights

These vehicles are being recalled because the headlamp driver module (HDM) can overheat and fail. This will cause the headlights and daytime running lights to stop working. Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.

Power Door Locks And Windows Do Not Operate

The module that operates the power window and lock switches can allow moisture in, causing corrosion that can lead to a short circuit. This results in window and lock functions not working, and creates a fire risk. Dealers will inspect and replace affected modules free of charge to resolve the concern.

The rear suspension is ...
Overall I really like my SUV. Has 140,200 miles. I am second owner with 27,000 miles. Spent money on the brakes. But now my problem is the lights. The automatic running lights will not turn off at times. Some time the dome lights will stay on and sometimes the lights won't come on. The Repair I use said that they can fix it but this problem has to be done at the Dealership. So, I am tr...
