I have an 07 Dakota standard. When I turn on the a/c it blows hot only, like heater hot. I can hear the flapper moving when I switch from hot to cold and the a/c clutch engages when I turn on the a/c but it only blows hot. There is plenty of Freon in the system. Could it be the switch that turns hot to cold?

It sure sounds like it moving though. I also have the temp dial turned to cold so why would heat come through?
