Ok so I have a 99 GMC Suburban K1500.
The problem I’m having with my left tail light is that it…
- No Turn Signal
- When My Head Lights are off and the brake is pressed, the left brake light doesn’t work
I tried replacing the bulbs which was my first best guess. ( I did notice that one of the sockets looked burnt out ). Tested it out and still no turn signal. But the brake lights worked.
So a buddy of mine told me that it may be the turn signal flasher…So I went out and brought a replacement. Switched it out and still nothing. But in addition to this the brake lights would only come on unless I turn the head lights on.
Now I will say this…I just recently installed an amp and a subwoofer which required me to remove the dash so I could complete the wiring. Do you think that maybe I could have accidentally hit something like a wire or whatever causing me to have this issue? Also…before I replaced the flasher the turn signal and brake light DID work one early morning on my way to work but shortly afterwards it stopped.
I hope that this is an easy fix because it’s becoming very annoying and I really hate to drive like this. Any help or advice would be greatly appreciated!
