The search function here is terrible these days. I'm trying to find out what the oem CCRM part number is and if there are any others that are usable as well. It looks like 1R3Z-12B577-AA is the oem part number. I found a few on ebay with the same core 12B577 number but the first 4 and last 2 characters are different. They are listed as working for 99-04 mustangs. Not sure if the Cobra is different for this part.
Some background on my problem. I'm trying to figure out why my high speed fan isn't working when the AC turns on. The low and high speed fan works properly based on engine temperature, but when i turn the AC on, only the low speed fan comes on unless the high speed is triggered by temperature. I believe the high speed fan should turn on with the AC clutch regardless of engine temp.
Thanks.
