Hi! Been a while since I've been here! I am in search of a diagram for the fuse box on my 1988 GMC K1500. I have no power to the lighter. The other day, I read somewhere, that the fuse is the CRSY fuse. I took that fuse out, disconnected the battery and cleaned the lighter connection in the back..

Typical electrical problems include bad batteries, alternators, and starters, along with blown fuses and bad battery cables. Some wiring system issues are more complex.
Here is where to find the fuse box on a 1988 to 98 Chevrolet pick up truck. If you have a Chevrolet pick up truck and you are trying to find a fuse box, this.. You are my Hero! That clears up just about every question I had The only thing that would make it better is a diagram of the 95 convenience center like the one you provided. but I will take and back trace those with the volt meter from the fuse box to the center. Thanks you again for the quick response and the awesome explanation.
