I recently picked up an LED modded 89+ climate control for my 87... dude said it worked perfectly... such is not the case... I installed it the other day and turned my lights on and blew a fuse. I put in a 25amp fuse and as soon as the parking lights went on... pop!. Apparently this guy sold it because it has a short... anyone knowledgeable enough to fix it or at least steer me to some helpful knowledge?
