Good morning, I'm need to buy a CCRM type L serial number F1SF-12B577-AA for my 93 Thunderbird SC, if you have one in good working condition please let me know, send pictures if possible. if you know where to buy one let me know too, Thank you
 
I know it's old just posting in case someone else ends up here with no info in the thread.

89-90 is one version PN E9SZ-12B577-AA or E9SZ-12B577-AB. 91-92 version is PN F1SF 12B577-AA. Don't remember about the 93 SC's for sure but I think they use the 91-92 version. Then the 94-95 versions are different as well PN F4SZ-12B577-AB. I listed the actual part numbers vs. the Engineering number which would be a E9SF, F1SF and F4SF as the prefix and what you see on the sticker of the part. There is no difference I am aware of for manual tranny cars vs. auto's as far as the IRCM's are concerned.

The main problem with these is just the three relays inside. The relay part number itself is Siemens V23134-b52-x57 (FORD #E8DF-14A640-AA) which is a 12 volt 40 amp, 4 post relay soldered to the PC board.
If your a/c compressor suddenly quits after a while, then comes back on, this is your problem. The relay will heat up and cut out, then come back when it cools.
