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.

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 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.

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