Hi Guys, new to this forum. I have a couple questions:
1. Does anyone know how I can get the factory Electrical manual or Circuit Diagram manual for my 1998 GMC Sonoma 4.3L Extended Cab 3 Dr.
2. After I remove the mounting bolts on the underhood fuse box I loosen the the 7mm bolts under it but it won't come off. I don't know if its designed not to come out. I wanted to open the fuse box and inspect the fuse terminal relating to the 3rd brake light (High Mounted Stop Light). My circuit tester has very faint light indicating low power. The Relay has power.
Thanks in advance.
