944 a/c fuse
 

I have an 84 944 and a 25 amp a/c fuse keeps blowing on me. I dont believe it is the compressor, because the fuse blows as soon as the a/c switch is turned on even if the engine is not on. The cooling fans turn on, but not the in dash fan. Also is the in dash fan for the a/c and the heater the same. Thanks

No, you have two separate fans. The one under the hood in the middle on the fire wall is your fresh air/heat fan. It is controlled by the small knob next to the climate levers. The other fan is for the A/C, and is in dash. It sounds like you have a wiring problem going to the in dash fan, or a bad fan motor.

Ah hah, I will try to trace that underdash fan down and check its resistance. Thanks.
