Re: Cluster of Exterior Lights Out, Help Please!
 

The only problem with checking the LR Park fuse is that it is for the left rear only :( but it is a start to try and get ya fixed :)

Crossing fingers for ya though that ya find a bad fuse or two.

As for the relay, you might want to swap out the starter relay for the park relay and since ya don't have to start the truck, try the lights then, just a thought.

Good luck, Ed

Hey I am pleased to report that the LR Park fuse was in fact blown. I replaced that fuse and that fixed 90% of my problem. The driver side yellow signal light is still out. I swapped the passenger side light for the dirver side light and it does work.

Looking at the driver side front signal light closer, it does work but very dim. From what I can tell there is no bulb but its a LED and the entire unit must be replaced. Now I need to find one.

Info from the back of the part says:
GM 15114678 12.8 volts
