I noticed today that on my 95 the heater /ac fan runs always. the digital read out for my temp is ooc but the fan runs even in the off position. Anyhelp would be appreciated.
 
Two possibilities.

#1 - The resistor module for the fan has failed, allowing the fan to run full speed at all times.

#2 - A faulty ground is grounding out the wires to the fan, bypassing the switch. Fans are switched via the ground wire, so if the wire casing wears through, allowing the wire to ground out, the fan will run.
 
thanks for the help. I went back and checked and found a blown fuse in the fuse box under the dash. The one labeled run.

Doh!

That would do it.
