View Full Version : 12B577 Multi-Function Relay Control

If anyone knows who makes a replacement for Ford part #F6SZ-12B577-BA (or F1SF-12B577-AA). It is a relay control module, located just in front of the air cleaner on my 1993 SC and behind the R headlight. It has the cooling fan relay in it and apparently it has to be replaced as one unit (you can't just replace one relay) I have been told that there is a cross reference number of RCM19, but have been unable to find anything with that number.
I would prefer to find a replacement rather than a used one, but I will take anything.

That module is also called the IRCM, I have a used one off of my 89. I'll send you a PM.

An 89 and a 93 IRCM are different part #'s. In order to get the correct one I would post the # you have on yours.
