98 Mustang CCRM??

Constant Control Relay Module.
Symptom is no power to AC compressor clutch.
Does this sound right and where to get one?? Thanks, Scott

yeah sounds right... you can also jump the high side pressure switch to see if it comes on.. but the CCRM also controls the fan speed

Thanks for the reply. Which wires do you jump on the high press. swithch? I think there's like 4 wires on it. Don't have the schematic in front of me.

open the ccrm and look for the bad solder (burn mark).
wipe it off and resolder.
