There are reports of failures of the CCRM or Constant Control Relay Module. The CCRM has relays and switches inside that control or provide power to the engine cooling fan, AC clutch (to engage the AC compressor), fuel pump and powertrain control module (PCM). Single switches or relays can fail internally causing a number of different symptoms including no start conditions (inoperative fuel pump or PCM), engine running warm due to inoperative cooling fan, or the AC might not blow cold air.
The Constant Control Relay Module May Fail on Ford Escort

Started running crazy then died wouldnt start again had it looked at the Relay Module was replaced ran for about two days wouldnt start again it like the computer went out again Also when it started having problems the cooling fan would just run had to remove the fuse to stop it. What would cause this computer to fail again???
I'm not sure this is the problem however it fits better than anything else. A/C began to work intermittently over the summer and then quit entirely; the compressor comes on but no cool air. Mechanic told me its not the compressor nor does it need freon. I'll deal with it next summer ;).

A/C CLUTCH WOULDN'T CYCLE I REMOVED CCRM, DRILLED RIVETS, REMOVED COVER,LOOKED OVER THE INSIDE REAL GOOD, TESTED A FEW CONNECTION WITH A OHM. METER BUT THE PROBLEM DIDN'T SHOW UP TIL I HOOKED IT BACK UP WITH THE COVER OFF AND HAD SOME ONE TURN ON THE A/C AND SAW A SPARK FROM A SOLDERED JOINT ON ONE OF THE RELAYS.I MADE REPAIR AND BOLTED THE COVER BACK ON.
a/c compressor won't stop working, even if the a/c switch is on off. Mechanic told me to replace the CCRM

The air conditioning fan, heater fan, defrost fan all of a sudden quit working. Took it to a local shop after checking ALL of the fuses and was told the CRM needed replaced ($85 diagnostics an $400 repair). I am looking into purchasing the part myself and doing the repair... any suggestions would be most appreciated.

Overheating due to cooling fan not coming on
My control relay module caught fire. I replaced it with a used relay control module and has been working fine since!

Car will not produce cold air. Took to the shop and have been told that it is the Constent Control Relay Mogel.

The AC would cut in and out...sometimes blowing just air, sometimes blowing cold. Because of this I couldn't drive in the rain because the windshield wouldn't de-fog either. I took it in today for repair. They said it was the 'Integrated Relay'. They put a new one on and they said it was fine. I got one mile away and it stopped working again. Took it back. They were a little confused over it. So they went to pick up another integrated relay, and this one worked fine. The first one they installed was bad a bad part...and they got it new from the Ford dealer just this morning. They said there seems to be a fault in them and they have seen many bad ones. Lucky me, huh?
my a/c compressor stopped working, also having problems with hesitation while driving and sometimes while idling.Haven't found a solution yet, will try this ccrm module.

new pump , got power and ground to all wires at pump but pump will not kick on

A/c clutch wouldn't engage, troubleshot wiring back to the CCRM. Drilled out the rivets and visually inspected the relays and board, but it looked fine. Jumped power to the clutch wire and it engages. Went ahead and replaced the CCRM, problem solved. A/C works, and it runs 100% better also. I suspect the fuel pump relay in the CCRM was dropping voltage to the fuel pump also. I don't understand why Ford would use something like this for simple functions when other manufacturers just put relays in the fuse box. Obviously some engineer trying to pat himself on the back for designing a Swiss watch mechanism when a sun dial would work just fine. I mean it's an escort, not a luxury limo.
