I have exactly what MBDoc described -- warmer on the driver side, but not quite hot. Cold on the passenger side. Maybe I'll try adding a little of my own refrigerant, and then I'll just go in and suck up the cash for an evac and recharge if that doesn't help at all. I already took the duovalve all apart (thanks for that, ParrotofDoom), and found no obvious problems there.

It's definitely that time of year down here - plenty of A/C complaints will be posted the next few months! 92 degrees here this afternoon...not too hot yet.

Cheers, John
