The air conditioner radiator fan will not come on resulting in engine overheating when air conditioner is running at slow vehicle speeds or idling. I replaced a relay with no effect.

Your vehicle has 3 cooling fan relays. Have you inspected all 3 relays?

I checked the other two relays. Removing them stopped the main engine cooling fan. I assumed they had nothing to do with the a/c cooling fan. Am I wrong? The relay I replaced was black, with five, not four prongs. The others are grey with four prongs. Do you think replacing the other two relays would help?

Test the fan motor to ensure it works. Supply 12v power to it and see if it comes on
