I just bought a 07 Suburban LTZ. The front passenger turn signal is lit but won't blink. The passenger mirror turn signal also doesn't work. I have changed the bulb and still nothing. My dome lights also don't work. I can manually turn them on by pushing each individual button but when I open the door or turn the **** I get nothing. Any ideas on how to fix these issues?

Thanks

 

Welcome to the forum.

Might try a "reboot" by disconnecting the battery for 10-20 minutes. Others here will probably have a more insightful suggestion.

 

I tried the battery thing and no luck. The dealership said maybe the door button on the door jam might be broken. I don't see one. Can someone tell me where it is or show me a pic of what it looks like.

Thanks

 

I had the similiar issue in my daughters 2005 Cobalt...take out the headlight housings and switch the turn signals bulbs out, if the problem still persists, then its your wiring harness to the headlight assembly. Unfortunately, to fix it you'll have to replace the entire headlight assembly because gm doesn't sell the wire harness separatley.

Your problem with the dome light is your door switch. I would guess if you open your back doors, your dome light comes on. There is a door pin that activates the dome lights at every door. My guess is your front door pins need replaced.
