Default Re: 94 GT (Modified) Overheats with A/C on

The CCM module controls the fan speeds and which speed the fan should fun. Do the test above and if the fan does not run on high speed you can push a straight pin through the wire and check for 12v to ground with a DVM. If voltage is there you have a bad fan. if no voltage you have a bad CCM module. I had the low fan speed relay in the CCM module go out on mine. Must be careful to not allow the pin to touch any metal. The wires and fuse on the fan circuit is big. Short will make a big mess.
Good luck..
