My daughter has an '89 Tempo, on which the radiator cooling fan has stopped working. The Haynes service manual says that there are three different components involved with this circuit:
- Cooling Fan Control Module (inside glovebox)
- Radiator Fan Control Relay (inside engine compartment, next to left headlight)
- Coolant Temp Sensor (on housing near thermostat)
My question is, which one of these is *most* likely to be bad? I'm asking because the first item is $48.00, the second is $50.00, and the third is about $18.00. The manual doesn't show how to test any of these components, and I don't want to replace a working component (since they can't be returned once purchased). And, I don't want to spend over $100 to replace all three if two of 'em don't need to be replaced.
Any advice appreciated!!! Thanks......
