Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
This is usually caused by a common fault with the hazard button itself.This shorts out in the multi function switch causing this issue.Try activating and deactivating or jiggling the hazard button when this occurs and if it then blinks even briefly then the hazard button needs replaced.You can obtain just the hazard button from a local dealer or parts store and it pops out from the top and the new one installs in place.
If it continues to act up and doesnt try and operate at all when this is tried let me know,but this was a very common fault on this model to where GM made it to where just the button could be replaced instead of the entire switch assembly.

I apologize,is the engine not starting as well here?
Does the left front directional blink with this issue here?
O.k.,both left and right rear lights use the same ground.If there is an issue with the splice to the rear left light for the ground signal this issue can occur.Try removing the left rear light and jumping a ground to the black wire and see if this corrects the fault.If it does then the black wire needs inspected to locate and repair the ground source issue.This ground for the rear is ground G450.
Ground G111 is the ground for the left front light assembly.You can try and jump a ground to this black wire as well and see if it corrects the fault.If it does then the issue is with the front light black wire to the ground source.
G111 is located Forward lamps harness, to the left of the radiator support
G450 is located Body harness, in the LH Rear body comer, near C403 to the tail lamp harness
Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.Your 5 star rating is appreciated
I dont show any diagrams on the grounds themselves but the rear ground is located near C 403 and below is a diagram for the location of C403.
You can try a dealer to see if they can sell this connector still but usually due to the year you may need to obtain it from a salvage yard or splice the wiring together unfortunately.
The no start is a separate question so it would have to be opened as a new question unfortunately.You can however request me or put my name in the first few letters of the question so I can see it to answer it.
