No Power to Compressor on 1997 and Later Escort and Tracer

For reasons yet unknown, we've been seeing 1997 and later Ford Escorts and Mercury Tracers coming in with electrically dead A/C compressors.  You check the system and it's always the same: the refrigerant level is fine and all fuses and relays are OK. Jumping the low pressure switch does nothing.

Suspected Cause:  Though we don't exactly know why electric current is interrupted between the low pressure safety switch and the compressor.  We suspect that excessive heat within the harness is damaging a connector or maybe even the wires themselves.

The Fix...

    I'm having what appears to be a similar problem with my 2002 Explorer. This article gives me something to investigate and possibly avoid the common "buy another compressor" solution offered by repair scammers.

    Great Job! Thank You so much, 7 Auto Shops gave me at least $700.00 to 1,000.00 to repair the problem. Now I have my ammo and I will get the proper repair. Thank You nd God Bless

    The cause for this no-power situation is a defective A/C relay in the CCRM module located below the lower air cleaner housing. This is documented elsewhere; search Google for "escort CCRM". This module is mechanically identical for all 97-03 Ford applications, but the part numbers vary, and the internal wiring differs drastically. The part number label on the cover of the CCRM has a large single letter, e.g., "R" for the '97 Escort. This same letter must appear on the replacement CCRM, even if the part number itself has changed because of manufacturing changes. The modules cost from $100-250 at a Ford dealership, but the module may be opened up and the defective A/C relay replaced or the cold solder joint fixed as described in several articles on for as little as $10.
