For some odd reason my A/C only works if I put it on "Max Cold" 65 degrees.
If I move it any higher hot air blows out??

Any help.. its driving me bonkers.

Thanks

could be your interior temp sensor is either clogged, or not plugged in. Its right above the drivers right knee behind a little small screen.

Open it up, clean it, or make sure its plugged in.

Ahh haa.

Will check that out this weekend.
Thanks
I hope that is what it is.
I noticed it after I had an aftermarket gps system put in.
I bet the installer unplugged something.
Thanks

Thank You!! that was it! The installer probably didn't plug it in.
It was just hanging there. Plugged it in and now it works!!

Here is an A/C tip in the winter run the compressor you can have on the heat and turn on the ac switch for about 5 to 10 minutes. This helps the oil and freon mix keeping your A/C system running for years. When you turn on the A/C compressor it will not get cold the heat will keep it warm unless you turn down the temp then it will really get cold.
