A few things that happened when I turned on my AC this morning:

1) The air felt like it was 75 degrees regardless of increasing or decreasing the temp. I only felt a difference when I hit the two temperature extremes, which was 60 and 90 degrees. So basically I have to turn it way up or way down to get AC or heat.

2)After restarting the car, I turned on the AC again and this time there was constant AC until I turned the temp up to 90 degrees. That's when the AC stopped and heated air came out.

3)A few times I pushed the manual button, the unit changed back to auto/econ mode automatically.

4)It was changing modes while I was playing with the temperature adjustment.

All these problems were experienced was with the AC button on.

Have anyone on this board had the same problems????

only problem i've heard with AC's were aftermarket intakes rubbing on the AC line.
otherwise, someone else can shed some light on this.
if u have no aftermarket electrical components interfering w/ur AC, then take it to the dealer.

 

Yea I was thinking the same thing when I first read your post header. If you do in fact have a aftermarket intake you should make sure its not putting a hole in your A/c Line.
