Ok, so here is my problem. I cannot get my radiator cooling fan to come on unless I direct wire it. I just replaced my condensor fan motor, and was thinking my radiator fan might need the relay replaced? It doesn't come on even after the car is turned off. It used to, but doesn't anymore. Any thoughts?

 

also check your thermostat.

 

Welcome in,if it only runs when straight wired then it must be the relay.
