Hello everyone. I have a 2007 Dodge Caravan with about 200,000 kilometers. Recently I've been overheating just sitting in traffic. The fan circuit check engine light is on. I have changed the following parts: coolant temperature sensor, entire radiator fan assembly, thermostat, 40 amp fuse (it was blown) and fan control relay. Yet the fans just won't turn on.
I tested the fan relay plug with a test light. Everything works except for the last one that gets a signal from the ECU telling it to turn the fan on. I waited for the car to get up to 220 Fahrenheit and still couldn't get a signal from the ECU. I jumped the two big wires and the fans turned on.
Any advice would be appreciated. Thank you.
