The Constant Control Relay Module May Fail on Ford Escort

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.
