Just bought a 2012 Ram 1500 quad cab with a 4.7.
When AC is turned on the check engine light comes on.
Fault code is p0481 which is cooling circuit II malfunction.
Electric fan isn't coming on.
Checked all fuses and they're good.
I switched the power window relay out with the fan relay and the power windows still work so I don't think it's the relay.
Unplugged fan and ran battery wire directly and the fan comes on.
I pulled the relay from the rad support and bypassed it and the fan comes on.
I dont think its getting a signal to turn on.
Any suggestions would be welcome.
thanks
