Ok, so I have replaced my thermostat in the car to make sure it wasn't getting stuck. Then I had the smart idea to turn on the car with the A/C at max to see if the radiator cooling fan would kick on. It didn't. So I took a screwdriver and spun the blades on the fan a little bit. The fan started up. So what does this mean? Does it mean the fan motor needs replaced? Thank you very much!

It means you have a bad fan motor. We do the same thing sometimes to diagnose that. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

I guess that depends on how long your fingers were when you started. You should be able to get 3 or 4 cuts before you reach nubs. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Bad news, replaced the motor with a brand new one, still doing the same thing. You think there is a short? The horn isn't working either and I can hear a clicking sound every once in awhile like something is trying to turn on.

If you pushed the fan blade and it caused the motor to start, that pretty much points at nothing but a motor unless it wasn't you that started the motor. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

It still isn't turning on when the AC is on or temp gets high. What should I try next?
