Raditor Fan Not Turning On

[jusblaze77]

I am still trying to troubleshot my overheating issue. I notices that raditor fan in front of the car is not turning on when my car overheats. Does any one know what could be causing it not to. I have check the fuses but are not certain how check the relays or what ones o check?

auxiliary fan switch

turn on the a/c and see if the auxiliary fan comes on.

if it does then your switch is probably bad.

if it doesn't , then check fuses/relays
