Default Radiator Fan Problems (again)

2007 Pt Cruiser. My wifes fan motor has been replaced twice by two different shops and it has quit working again. So I pulled it myself this time to see what I could find. The fan itself is still working on low and high if I jump it directly from the fan motor itslef. Any suggestion why it wouldnt run when connected thruogh the relays and is there any way to jump it and check from the connector that unplugs from the harness at the car itself. Also where can I find the temp sensor and could this be a problem.

Yes, you can hook up a ground and positive wire to the electrical connection that unplugs from the harness. The middle pin is ground and the two outter pins should make the low and high speed fan come on.

How do you know the relays are good? But to tell the truth, I can't remember anyones relays being the problems when the fan doesn't come on.

The ECT (Temperature Senser/valve) is located under the thermostat housing. Like the picture below only in the 2006 and newer cruiser, for some unknown reason, they seem to be put in facing the opposite from this picture which makes it harder to get to. It can have an affect on when the fan comes on, but the biggest thing that may have a problem is the computer.

When everything is cold, turn on the engine and the A/C. The low speed fan should come on when the A/C is engaged. If not, the computer might be at fault. A true test would be to hook up the car to a DRB scanner that can go through all the functions and tell if the computer is working.
