I just got done doing a camshaft job on a 2011 1500 5.7 everything is good so far however the a/c condenser/cooling fan Is not working code p0481 fan control circut/open. I jumped out the fan and it works so its good I checked all fuses and determined I have no power going to the green and black wire at the fan but have power to the blue wire that is not used plug has 3 wires but fan has 2. I can command the fan on with my scantool and hear the relay click swaped it out but no change no power on the 2 wires. I tried to trace the wires from the plug back to the tipm but cant figure out where they go i need to know where the power comes from for the fan any suggestions appreciated.

Doesn't it get the signal from the ECM, check the connections.

So the signal from ECM is reaching the TIPM because the relay clicks just cant get power to the plug trying to find out where those wires go so i can test. I tried to trace em but goes into main harness will be a mess if i have to tear it all apart.

Are you sure the relay on the TPM is good can you use a jumper to bypass the relay, the relay is soldered onto the circuit board, much luck Sir!!!
