Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
Does it start and run?
You can choose either of the sensors and connect it to the yellow and black wires of the vehicle harness then just not use the other sensor.
Let me know how I can help
If you short the sensor connector together with a paperclip does the fan come on?
Do you know if the coolant is full?
Do you have a check engine light on? If you do what is the code?
The check gauge should be for the temp gauge but if you have a wrench or service engine soon that needs to be diagnosed.
Let me know what you find tomorrow, I plan on being here
You said the temp gauge does not work in your question?
I am confused
Ok, so as long as you connect the yellow and black wire to one of the sensors the computer will know what the temp is, from there it is a matter of the computer grounding a relay to turn the fan on.
The temp gauge is fed from the computer so we assume the sensor and the computer are working. You need the relay and the fan motor to work.
Try the paperclip or turn the AC on if it works and see if the fan is running, if it does not try powering the fan directly. They do fail.
