My A/C will be blowing just fine and cooling both sides. When I get to a fairly humid climate (San Antonio) my A/C will exhibit a reduced air flow(sporadically) and an increase in temperature on the passenger side (drivers side always stays cool). When I turn off the A/C and the recirculation button, the air flow will return to normal. The A/C will also continue to produce cold air for a short time and eventually blow air at the outside temp. When the air does blow at a normal rate with the A/C on, it is at a cool temp. My refrigerant charge is fine or just a wee bit high. My drier does not show any signs of icing up when this is occurring. Thanks for your advice.

I'm betting the evaporator is freezing up.

Things to check are the charge level, that the HVAC case drain is clear (on the firewall on the passenger side, you can spray compressed air up there, or even briefly hit it with a garden hose and let the water run back out).

Dealers also sometimes relocate the temp probe, but I'm not sure how exactly they move it (maybe bend it so it is closer to the evap?).

Seems to be alot of A/C problems on here today.
Hey as much as I've been referring their product maybe I need to call them and get a commission check.
