Default Re: 01 pt cruiser radiator fan not working HELP

Salteedog,

As Doverdale found out, sometimes it's not a part that can easily be replaced but something that's not part of the equation of how the fan works like a bad wire. The two things you haven't tried (but mentioned one) is the ECT (Engine Coolant Temperature) sensor and the computer. They both have parts to play in operating the fan and keeping the car cool.

One thing to tell you is that when you hear the compressor going on and off repeatedly, it possibly means your low of R134a so yo want to have that checked.

Also on the overheating; are you using the right coolant in the radiator and at the proper 50/50 mixture? Are you sure all the air is out of the system?

I find it ironic that the colors red, white, and blue stand for freedom until they are flashing behind you.
