A/C blows a fuse

[Shane]

I have only had my MJ for 2 months. I' ve had it painted. The previous owner said that the a/c works, but it blows a fuse and he said it was the wiring harness. I'm definately not a electrical person. I have not treid to run the a/c. What happens when it blows a fuse? Does the a/c still work, does it cause the truck not to start or what? How hard is it to fix? Thanks

That is quite a loaded question. It depends on what is causing the fuse to blow, but it's not very likely that the AC will work if a fuse is blown. The blower motor itself may be bad and causing it to blow or there is a short in the wiring somewhere that is going to have to be traced and repaired.

 

I hate electrical problems as they can take forever to figure out and I am not good with electronics at all :mad:

I would start by running the AC to see which fuse blows. Either the fuse block itself or the manual (or both) will say what that fuse is for, and what size belongs in there..
