Well, this is an old problem, and since I'm almost done completely fixing my Blazer, I figure I had better go ahead and take care of it. That problem is, my dome lamp and courtesy lamps do not work. The dash lights work, and I think the rear dome light near the back glass works, but not the others. I've checked my wiring diagrams, and checked all my fuses. No good, the bulbs were bad, but I put a meter on it and I have no voltage on the dome light. Suggestions?

 

I am having this problem also! Can anyone help?

 

Could be a broken wire somewhere, since your not getting power to the lamp. Try tracing the wiring and see if you come across anything.
