[QUOTE="machoheadgames, post: 437820, member: 18789"] Many times the blower motor itself goes bad and shorts the system. You haven't replaced the blower motor, right? If it were me, I'd depin the blower motor connector (on top of the lower heater box behind the glove box), then hook up some alligator clip leads to the wires going to the motor and then run those to a battery. Put a fuse on the positive so that you don't cause an unfused short and burn the Jeep down. See if the motor powers on, if it doesn't, it would have blown the fuse again, if it does then you still have a wiring problem hidden somewhere. It is quite a simple wiring diagram, so other than the power wires being tucked in the loom from the battery all the way to the bulkhead on the firewall, it shouldn't be [I]that[/I] difficult to find the problem. I've attached the blower motor wiring diagram just in case you aren't already referencing it. [/QUOTE]
