Help please
driver side switch for pass side front window not working, but pass side switch still working, checked fuses, not blown. Also, when shifting out of park, rear doors are locking but front doors are not automatically locking (and that is the mode that is selected). I am very much a novice and have virtually no tech knowledge.
To rehash:
1. Driver side switch for front pass. window not operating, but front pass switch is still lowering window.
2. Front driv and pass locks not locking when shifted out of park, but rear doors ARE still auto locking.

Thanks

 

I had this happen to me once. The way I resolved it was 1) Use the remote to lock the vehicle, and 2) use the remote to unlock the vehicle. Since then, the problem hasn't come back.

 

I'd try disconnecting the battery maybe a control module is confused just and easy place to start

 

Welcome to the Tahoe forum.

I had a similar problem and they had to replace a module under the dash.

 

Marc was it the BMC or a module in general?

oops BCM is what i meant...

 

Per the repair order, it was called the "IP fuse block with internal relay". They said the old relay was stuck. Not sure why the relay wasn't just a plug-in type but that's just GM I guess.
