You most likely have a bad water temp sensor (or bad connection to the sensor).

Back track the wires from the fan plug. One will go to the ac switch, and one goes to the temp sensor. Usually the water temp sensor is located on the radiator or thermostat housing.

You may even want to think about changing your radiator cap. The car could boil over and never get hot enough to trip the fan switch if the cap is faulty.

I have a Saturn 1992 SL Sedan with 164,000 miles. I am having a major problem with the car cutting off while I am driving at a fairly constant speed or when I am idling at a stop light. The engine will shut off, along with the power steering and all other electronics. This happens when at a stop light only after I press on the gas to accelerate from a dead stop, but I am able to put the car in neutral and start the car again (sometimes it takes a while to restart). We tried getting the electronic control module repaired, but this did not fix the problem. We checked the oil and it appears to be of the correct viscosity for the engine. We are at our ends as to what needs to be done to fix this dire problem. Thank you for your time! 8 Answers
