Or another random Idea I just thought of.... Where is your A/C drain located? Mine just has a 1/2" aluminum tubing stub a few inches out of the firewall going down... In theory it could be possible that at highway speeds there is a high pressure area at the back of the engine bay not allowing the condensation to drain properly. I may try extending my drain down under the car where again in theory it would create suction by the air passing under the car.
True that icing of the evap would cause a degredation of the cooling from the vents which I'm not getting but the car I'm dealing with is a convertible so you are never really cooling off like a full cabin car so for me it's hard to tell if I'm loosing cooling... need to get a battery in my dash temp gauge I haven't used in 10 yrs.

Good point.
Maybe I have never had an issue because I drain out to the side cowl vent (high suction area) and always have a down hill run on the line.
