My fan work sometimes and don't sometimes. The car is 98 Mustang 3.8. on 1998 Ford Mustang

After replaceing the fan didn't help I researched on the net and found it may be the CCRM. I have it off and would like to just replace the relay for the fan but can't find which relay it is. The CCRM is F6ZF-12B577-AA.
