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???

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.

Engine died while driving with simptons like running out of fuel. Would not restart. Has spark and fuel pressure. Will run while spraying fluid in the intake. What is probable cause.
a/c compressor won't stop working, even if the a/c switch is on off. Mechanic told me to replace the CCRM
after engine is off cooling fan keeps running shut off by removing fuse next day when cold fan runs with engine cold
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 ;).

Yes, its funny my problem started when I went to start my vehicle, and for the first time, I had trouble starting it, but it did start, then I noticed my fuel gauge didnot move off of 1/4 tank, and then and now the transmission does want to shift from third to fourth, now schematics that I have point to ECM, the ECM controls the shifting for the transmission, and I noticed also, it controls the fuel gauge, so how do I determine if its the transmission or the ECM causing this. Or something else completely, in short: how do I get this vehicle running again.
Overheating due to cooling fan not coming on

cooling fan running constant, won't shut off. now my fuel pump isn't getting any power.
cylinder will not fire although it seems to be getting fire.
Vehicle engines sputters and cuts outs after driving a few miles. It restarts usually with no problem, but will cut out soon again. When cutting out at times and pressing the gas pedal, there is no reaction.
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.

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 control relay module caught fire. I replaced it with a used relay control module and has been working fine since!
