So I get in the car...drive, AC seems to work fine...till about 20 minutes in, air gets warm...just like if I were to push the AC off button.

I turn the AC off, open the windows for a minute, turn it back on, and it works. Got Freon recharged, no freon leaks, confirmed. Problem persists.

Any ideas? Anyone else had this problem? I don't want to bring it in yet, cause i'm afraid it will work fine when i bring it in...and waste my time.

This is on the 2002 ML55.
