I have a 06 se Magnum. It isnt dual climate control. Whenever i start the car heat seeps out of the dash vents. the heat seeps out even with the **** turned completely to cold and the fan in the off position. if i leave it set to cold and turn fan to high it blows hot air as if i turned it to the heat side. it even blows the hot air for a couple mins if i turn the a/c on too. have no idea if switch may need to be replaced or if the internal door that switches from hot to cold isnt workin properly. Any ideas cuz i am clueless.
