Pusher fan not working when tempature is above normal but will work if i direct connect it to 12 volt source. Wondering if there is a sensor that as went bad or something. Any ideas?
 
What is "above normal"? I believe the pusher fan only comes on when the high speed puller fan comes on. If the puller is on low speed the pusher won't come on. Do you know if the pusher is not coming on with the high speed fan? Otherwise since you've already verified the motor itself is good I would look at the wiring and then the IRCM.
 
When i say normal i mean above the L in normal my check gauges light came on the other day because it got so hot. Had to turn AC on max so the puller fan would run constantly. Thought it was going to blow the engine. What is IRCM?
