Hi I have a 2005 chrysler 300 and my defrost not work properly. When I start it he work like 1 sec and after I hear a sound like a valve depressure and the air flow reduce. So my windows allways got fog

Check fuses and pull hvac fuse for 60 seconds it may fix it, otherwise check your actuator in the heater, it may be hanigng up or not getting power. You might try to align it and it may work. If not check for no power it should be on driver's side. Pic included.
