I have an 07 GP, 3.8. Looking for some help with an error code. Its a p0480,cooling fan circuit 1. Right side (passenger ) side runs constantly whenever engine is running, Temp runs normal., coolant/temp sensor/thermostat all good. Relays swaped, same condition exists. I know on some older/other models other sensors (MAF/MAP influenced PCM/fan operation. Tech help,wiring diagram relay/Pm pin IDs wuld help.

Thanks
