driver side trailer lights not working (GMC Sierra)
stewie:
I did a bunch of searching on the issue and some are saying a short others a fuse, but i cannot find in the fuse box where left/right brake & signal lights are. i just see lights and brakes.
Am I looking in the wrong spot? i dont think it's the trailer because my suburban was recently towing it and all the lights worked.
stewie:
its dark out now so i went out and was able to troubleshoot better. all the lights go on but the left light wont flash when i put on the turn signal. it will also not brighten when i apply the brake.
KensAuto:
The fuse is inside, by the driver's end of dash. They have separate fuses for left and right turn lights.
Scratch that...my '12, 3/4 ton says it's #3 fuse, under the hood fuse box
stewie:
just checked all the fuses.
i took the left light assembly off and inspected it. it gives a faint pulsing when i turn the hazards/turn signal on, but only for a few seconds. when i unloack truck it lights up, but when i lock (pulsating) it doesn't.
is s a bad light assembly?
KensAuto:
I would say a bad ground on that bulb, but not if it works fine on the burb. Try wiggling the plug?
