I have already replaced the engine coolant temperature sensor and both fan relays. I have tested the wires from the sensor to the ECM and ground and they are good. The fans come on 100% when I unplug the coolant temperature sensor for safe mode. I also replaced the relay for the air conditioner compressor and that system works correctly (I read that the two systems are connected).
I am at a loss, any help would be wonderful.
have the same problem?
