AC works fine for a while - a few minutes, a few miles. Sometimes 20 miles. Then - no cold air. Compressor still running. Blower fine. Press button to turn off AC. Wait 4 or 5 minutes. Press button again,works fine. Rinse and repeat. Hotter the ambient temp, worse this problem is. Quest recharge / diag tool just gives error light with no real indication of what is wrong. Overcharge? Undercharge? Tried putting freon in, takign it out. Suspect some soret of pressure / temp sensor or something. Really uncomfortable in summer traffic jams!
