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

Still amazes me that those 210s do that.

Evidently if the refrigerant is low, the cooling in the evap gets "all used up" before it gets all the way across.
