I have a 95 Mystique and I am having problems with my cooling fan. I have replaced the fan, I have replaced the TPS. I know the wiring is good to the fan motor. I can jump across wires at the fan relay in the fuse box and the fan runs, but when I hook it up and run it normal the fan nevers comes on. Does anyone have any ideas what else I could check to see if I can fix this problem.


Thanks

 

TPS? throttle position sensor?





there should be an electronic trigger...

 

There may have been a recall for this problem if you give me your vin I can check to see if any recalls for this problem are out there for your vehicle.

 

First off I want to Thank everyone that sent a response to my problem. But I was wondering what Patrick was indicating when he stated that it might be the TPS.
More Info:
The fan runs with the A/C on.
If I unplug the Temp send unit the fan comes on at full high speed.
I have traced power to all of the fuses and the wiring is all good.
The thermostat is opening.

What temp does the fan come on at ?
I am going to but the book called "Ford electrical Vacuum diagram troubleshooting manual. Does anyone have this book, and is it any good for overall problem solving. I have found the hanes book is not helpful at all.
Once again thank you to anyone that may be able to solve this problem, I have everyone scratching their heads around here.

Thanks
