P0480 Relay control side was created by operatorerror
2010 Chrysler T&C 4.0L Code
P0480; Fan Control Circuit 1 Open.

1 Fuses and Relays are good
2 Power to pin 30 relay load, and pin 85 relay control.   
3 High speed fan works. 
     What ground(s)  pin 86 in the TIPM?  I hope I worded that right.  There is some sort of self check at start up.  About 2 min in the fan will turn on high and the check engine light comes on.  I can clear the light and it will repeat. I can turn on low fan by pushing the load side of the relay(Pin 30 to 87). I believe this also lets me know the resistor is good.  So I feel this tells me there is something not working in the TIPM, or what ever it needs to command ground.  Fan does not come on when I turn the a/c on.  The a/c clutch does engage and work.   Thanks for your time.
