Air Conditioning problem
 
I have 2003 Grand Cherokee.

The air conditioning starts but after about 40 min of riving it just blows hot air. If i turn the car off then turn it back on the AC starts working again, but for only about another 30 minuets.

Replace both your high side and low side pressure switches and do an AC service. One of them is bad.

Do you mean that you turn the motor off and immediately restart it and the AC will work properly for another 30 minutes or so? Or do you have to let it sit awhile before restarting?

Turn off and immediately turn it back on it works again.
