Hello all, I am needing some technical support Please. I have an early 1999 Escort ZX2, Mfg. 11-98 with 2.0 DOHC and auto. The CCRM (Constant Control Relay Module) is bad and will not send power to the A/C compressor. I have power at PIN # 21 and #22 but no power at #23 on the CCRM. I found a used CCRM for sale from a 97 or 98 ZX2 according to the seller.He is not sure of the year. The part # on his CCRM is F6SF-12B577-AA. The part # on my CCRM is F8CF-12B577-AC. I know that the CCRM I need must be for a 98 or early 99 ZX2 because they changed the wiring for the A/C circuit after 2/14/99 thus changing the CCRM. Apparently the one I found for sale is from a 97 model and I can not find any info saying if it will work or not. One mechanic said that it might be what is called a ICRM that is basically the same thing but wired for earlier model escorts. I checked with parts dept. at the local Ford dealer, all he could do was tell me that he could sell me a New one for $182.00. One so called expert had the nerve to tell me to buy it and try it, if it works great, and if it don't you only lost a few bucks. I really don't want to fry something like the Computer ya know.
Any and or all help is Greatly appreciated.

This info is way too late for you but someone may benefit from it:

You can remove theCCRM and disassemble it and look for cold solder joints on the circuit board. I got this tip from another board and just repaired my daughters CCRM allowing the AC to work as designed. All in all it took about 1 hour.

Evidently this is a common problem and little known fix. At $200 a pop, it is worth a look.

The CCRM is under the air filter. A drill is needed to drill out the rivets allowing removal ofthe CCRM cover and to take the circuit board loose for inspection. Resolder any joints that look suspect - this particular cold solder joint was on the smallest relay - circuit board side. Do not try to take the relay apart, theyare not the problem.Anyone with basics skills should have no problem performing this fix.

Good luck

 

Can some one please tell me the color codes of the wires out of the ccrm module that control the air conditioner clutch?
