I have an 08 Suburban LTZ and the passenger side power mirror will just randomly adjust its self. It does not matter what key fob you have or what driver number you have pressed. Sometimes it points up, down, in, or out. Its just a craps shoot on what direction it goes. Any experience or ideas on what to test to fix it?

Thanks,
Charlie

 

Take it to a dealer and get the drivers and passenger door modules reprogrammed. GM released updated calibrations to address glitchy problems like that. Have them update the bcm and pcm and tcm as well if you are still on stock programming. Doesn't take much time at all to do.

 

Thanks for the info. I searched the interwebz to see if I could find info about it but nothing. I just didn't want to go to the dealer with no info and have them telling me I needed a new mirror at whatever rediculious they are charging.
