Hello there im new to this forum and need help with my 05 gmc envoy. I just had my envoy fail inspection because my corner lights dont work. So I need help on wat the purpose of the lights are and how I can fix them to work again

derrick

Are these the lights you are referring to?

Yes they are

They are out on both sides?

^ if they are both out-
The front parking lamps fuse is # 37 (located under the rear seat fuse panel)
Also have you tried replacing the bulbs?

Yes they're both not working and both bulbs been replaced. Beside the fuse box in the engine compartment and on the driver side theres 3 fuse boxes total

Did you just buy this car? Have they ever worked?

If I am not mistaken, those are "cornering lamps".......they only come on when the directionals are used....they don't flash, they just stay on.....when the directional for that side goes off, so does the cornering lamp on that side.......

If they previously worked, then the simplest thing to do is remove the bulb and attach a test light to harness, say left side.....turn key to on......turn left directional on....if test light doesn't light, then check the ground and power circuits individually....we know the fuse is good if your other park lamps work.....I doubt two different grounds would go bad at the same time, like wise the power feeds......so then it might be your turn signal/multifunction switch....

Thank you guys for the help it was the fuse I didn't know the envoy had 3 fuse box

Curious as to why the fuse blew in the first place.

I dont know this is the first time I owned a gmc and now have alot to learn bout this
