Hey! I looked at the fan wires and i think there is a jumper right there. I hate dealing with electrical so this isnt really my field. But, i cant think of what its called, but when u have a wire going in each end and its crimped, well theres a wire going from the fan back through the firewall and i think its for my stereo deck. Cuz at high volume, it cuts out and never at low volume. Weird because anything with stereo should be running off the batterty. I took two picts of that and a picture of that extra wire in the back coming off the upstream O2 sensor. Theres also an extra plug near the fuse box in the bottom coming out of the wire harness. If i can attach the pictures you will understand.
