I had a expansion tank burst on me recently. I do not know if the fan was related to that problem or not. The temp gauge never went over half when problem occured. However after putting in new tank I realized that the radiator fan is not coming on. I ran the car to the point of almost overheat to make sure that the fan wouldn't kick on at any point. The fan does however kick like it is trying to start about every minute or so while the car is running. It does not make a full rotation tho to give idea how little is moving. So here is my questions.
If the fan is bad, then far as I know this should put up a (DTC) and the engine light does not come up on dash. (Light has been tested to make sure is good)
How can that be? I even unplugged fan completely from the car and still didn't make light come on.
In trying to test the fan I noticed there are 3 wires. One hot wire, one ground, and a third. What is the 3rd wire for? Could it be related?
Any information would be very appreciated.
have the same problem?
