I don't know if any of you guys know, but I was playing with my pop's '95 Mustang GT today and it's throwing an error code 564 when we run an OBD diagnostic scan. I guess this is a fan control circuit or relay or something from what I've read, and it appears to be part of the CCRM on the side of the radiator. Do I have to replace the whole CCRM to get this thing working right?
