[QUOTE="01yellercobra, post: 17035695, member: 35549"] At this point I'd jump the fan from the battery. Make sure the high side works. If that's good then I'd let the engine idle up to temp with the fan disconnected and use a DMM to check the power at the plug from the CCRM. Make sure it's sending power when it's supposed to. If it's not then check the continuity. If continuity is good then you have to make sure the inputs to the CCRM are good. Which unless something went south with the ECU I don't see being an issue.
