I have done pinpoint test and I get to a point where its telling me to replace PCM , well I did that and guess what , still no fan , all wiring between PCM and CCRM is good , CCRM is new , PCM is new well (remanufactured)

I run pinpoint test with new PCM and says replace PCM , what are the chances I have 2 bad PCMs ?

Anybody got any ideas to check next , I am getting no other codes , should I try another PCM ? I dont know what else to check

Sounds like a fuse or relay, if in fact the PCM and CCRM are good, check those.

60 amp fuse is good and I have power at the CCRM on the pins that the power feeds to , checked all fuses inside the car and under the hood

So i checked all the grounds on the car, wire brushed and found the ground on the left side in front of the battery was striped. reground that and pulled the connector to the fan motor, sprayed it with some brake parts cleaner. connected everything back and VOILA!!! no check engine. hope this helps
