I need some assistance with these problems. I would prefer to fix myself before taking to the dealership. I have searched, of course, and cannot find what I need here.


1. Key fob not working. New battery and all. I seem to remember something about holding the "lock" and "unlock" buttons down together but could not locate it. So I tried it for a minute and nothing.

2. None of the electronic switches work on the passenger side front. This includes the window, and seat heaters.

3. When turning off the truck the electronics, ie radio, would still work for a few minutes. This does not happen anymore. When I turn off the truck, everything shuts down.

Thanks in advance.

customers whose vehicles are within the warranty coverage period and involved in
a product recall is very important in maintaining customer satisfaction. Dealers
are to ensure that these customers understand that shuttle service or some other

Dealers should refer to the General Motors Service Policies and Procedures

Thanks Klaus.

I asked the service writer to check for any TSB's. I think I will print this out and take it to him.

Any on an inoperative horn? I have had intermittent problems since I bought it.

Thanks again.
