Hi
my Dodge Caravan 2004 3.3L salon blower last 4 positions (from feet/windshild to windshild) works in the same way (feet/windshild) in all that 4 positions. It doesn't switch to 'only windshild'. I have checked other positions like just 'face' - works fine. What's the problem and how to fix it?

Thanks.

So the problem is with the defrost mode? The problem could be a mode door actuator or the door itself. You need to have the HVAC system for codes.
