Recently purchased a 2012 Ram slt Quad cab.Its Black with a 4.7 V8 and 6 inch lift with 35's.
I love the truck..When I turn on the Ac I'm getting check engine light.fault code p4081 which is cooling fan circuit 2 malfunction.
Has belt fan and electric fan but electric isn't coming on when ac is activated.Ive checked relays and I believe they are good.There is a relay on the top of the rad support which I think is the hi speed fan relay.when I bypass pin 30 and 86 the fan comes on.relay is brand new...any help on this would be much appreciated..thanks
