  Q: How to diagnose and address cooling fan issues on Chrysler Cirrus?

  A:

  If cooling fan issues are to be diagnosed and addressed, the functionality of its motor needs to be checked first. If the engine is overheating and the cooling fan doesn't come on, unplug the motor's electrical connector; then using fused jumper wires, connect it directly to the battery. Replace this motor if it still doesn't work. Each motor should be tested separately as they are connected to RFI module. The low-speed one has two-pin connector while high-speed one comes with three-pins connector. When the motor is okay but does not engage if the engine gets hot, there could be a problem with Coolant Temperature Sensor, wiring between these components or engine control computer and fan relays. The PCM receives resistance from the coolant temperature sensor located in thermostat housing that varies with temperature change. Take off fan relays and inspect their resistance. Inspect all wires and their connections carefully.
