Rear heat and air, blowers won't work.

[Codeman96]

I cannot get my rear heat and air blowers to run. If you put a fuse in it blows immediatly when the key is turned on. Where would be a good place to start looking for a dead short? Anyplace that this is common? Oh and it's an '84.

If your only blowing the fuse when you use the REAR heat and a/c then I'd start back in the back and work your way forward to the switch.
