It sounds like you may have a coolant leak or possibly a blown head gasket. If the engine is overheating it will shut the AC down to try and protect the engine.

Here is a guide on overheating and the casues

Here is a guide to find coolant leaks.

This will have you test for a blown head gasket.

If everything checks out okay it will probably be the ECT(engine coolant temperature sensor) if it's out of range the cooling will either run all the time, or not at all. May or may not set a codes.

Please let us know what happens.

Cheers

Thanks for the fast response. I will need to run some tests to see what's going on and will get back to you. I hear the fans running so I know that's not it.

Okay I run the tests you suggested (great guides BTW) and the engine came up with a blown head gasket (bummer) so I will have the work done and keep the car becasue this is the first problem I have had with it. It will cost me about $900.00 at the shop.

Thanks for your help 2CARPROS! I love you guys

Having the same problem with my 2007 TOrrent. In addition to the engine light coming on. The A/C off. The temp gauge does not move. But in very cold weather the vehicle completely shuts down. I need to pull off the battery cable to re-set before I can start it again. It has happened a couple of times and only in really cold weather.

We must get to the bottom of the over heating which is job 1. Check out this guide to help you find out what's going on.
