I have a 2006 gmc 1500 quad cab.my left brake light doesn't work.all other lights working normally. How do I check for short . My bulb is not the problem
Left rear brake light has blown two or three bulb. Now the bulb is not working
after replacement.i have owned this truck from new.
I have noticed that there seem to be some grounding issues with these trucks in the rear lights, so I would recommend that you check the wiring closely, make sure the ground is clean and tight, you should also check the sockets for a burn spot inside. HTH
