Radiator fan only turns on when AC is on
The radiator fans only work when the AC is on. So
the car slowly overheats when I don’t put the fans
on with the AC. I replaced Fan no.2 relay and Fan
no.3 relay, I replaced the thermostat, the coolant
temp sensor, and the coolant temperature switch. It
still overheats, could it be a corroded wire?
Suggestion....find the AC Pressure Sensor. Disconnect the two wires and jumper these two wires with a paper clip. Carefull now ...do not spread the connectors on these wires. I usually flatten the ends of the PC with a hammer. let the engine warm up and see what happens. Do not let the engine overheat.
Rad...how are those fans running? Fixed? Cause of the issue?
