GMC Envoy keyless remote problems
I own a 2002 GMC Envoy. Not sure what happened but all of sudden I can not use my keyless remote to lock or unlock my doors. I checked the batteries and they are not dead, but I can not open the back hatch or use the back windshield wiper or rear defrost. This happened once before and I thought I corrected going through the computer program for Driver 1 and Driver 2.
