When I put the air on dual air the passenger side will start getting hot speraticly. The dealer couldn't get it to happen the I pick up the car and head to Florida and about 7 to 8 times it did it. It got hot as hell. I finally figured out when I got back home that if it isn't on dual climat control there are no problems. What could cause this a thermostat on the passenger side or something else.

Check previous threads about the DCCV... :-) its doing the same thing on mine... I'm still trying to get an answer about if anyone has ever been able to clean it or if ya just have to shell out the $150 for a new one....

failing DCCV

DCCV. Move it to full hot and back to cold. The pass side should go to cold for a while (at least thats what mine does). It fails at random intervals and I live in Florida. Kind of annoying.
