CCRM woes

Steven · Jun 30, 2011

Having issues with CCRM. I have like 3 different ones. Each one with a bad portion. The one on the car, the fan would hardly if ever kick on. Then I just noticed that the AC clutch won't engage now. The other one the fan stayed on constantly. You could cycle the switch a few times and then it'd kick off when you started the car up. No problems with the fuel pump or PCM. However I did crack mine open to find someone took it upon themselves to solder in a new WAC and PCM relay. Going to the JY tomorrow to pick up a few of them to see if it makes any difference. The one I replaced the CCRM on the car with, was an old one I had from my old 95 GT which I believe had problems. Seems to be the case. My question mainly regards where the actual ground for the CCRM is located. I want to make sure it is up to par.

it probably grounds through the mount bolts and bracket.

after opening it up I don't really see any of the circuit board printing near the rivet holes that could possibly be for it. Hence why I think its through a wire.

Battery neg. comes in on pin 15
That goes to 3 of the 5 relays inside.
the other 2 relays go to the cooling fan relays, and they are gnd'd through the fan

Junkyard. Found a really clean V6 car that apparently kicked the bucket. Apparently the module in it had been replaced once before. Had a date from 01 on it. 94-00 mustangs use the same one, as well as 95-02 windstars. Pretty straight forward. I can buy a new ford one for 65 dollars shipped but this one was free so no complaints. Put it in yesterday and its been working great since
