Hi there. Welcome to our site!

This is one of those systems that make you wonder what the heck they were thinking about as they worked on it.

Please give me a couple of minutes to mull over the diagram and see if I can figure out a solution. Be right back!

Expert:  Juan Crespo replied 1 year ago.

I'm back.

I have a feeling the problem might be fuse 66 (30 amp - see attached graphic) in the underhood fuse box (GM calls it the "Underhood Electrical Center" - go figure...). Please check and see if there's current going through it and let me know.

Ok I will try that. Just looking at the diagram is the 71 fuse a 30 amp also so i could just swap and see for a quick check? Otherwise I will have to wait until the morning to go grab some test equip
Expert:  Juan Crespo replied 1 year ago.

71 is listed on the graphic I attached for you as a 40 amp fuse. It's never a good idea to replace a possibly burnt fuse with another one of even higher amperage. I think it'd be best if you waited until you got that test equipment

Best Regards
