2002 park ave heat on drivers side a/c on pass want a/c on drivers

Are you able to control the driver side air temperature at the dash registers? If not and you can control the passenger side of the dual climate system then you have an issue with the air temperature control door (moves between the heater core heated air and the AC evaporator cold air stream) deep inside the dash or the electric actuator that moves it or in most cases both.

I hope this helps.

should have buttons on your armrest or down on the side of the seat by the drivers door if not check in front of the seat

either the air duct under the dash is broken or diconnected, or you have a broken or disconnected vacume hose or line. unless you have seperate/digital controls for dr/pass air. if that is the case then you need to replace dr side control unit.

assuming you have an electronic controlled (digital) dual zone system, it is most likely your heater blend door motor has failed, check and see which side is operating and buy the one you need and replace, it has 2 or 3 screws on the side, i think size is 4.5 mm or 5.5 mm and you have to take off lower plastic cover under dash and remove screws which go on horizontally... install heater door with temp swithched to the middle, move door to middle, if not you need to place new motor into plug before installing and turn temp to cold, then turn by hand the white blend door tube to match motor then install... make sure you turn off ignition when working,,,

my a/c blows heated air out on passenger side and cold on driver side what is my solution to this problem

Behind the glove box you will see the heater box. On top of the heater box you will see a set of wires going to a small controller box that has an arm on it. It is probably not working and you can only by them at the dealer. It is the dual climate controller and cost approx. $100.

most likely you will be dealing with broken seat element. locate harness connector for heating element under seat and ck for power with test lite. just experienced same problem in a 2000 park ave

Check the operation of the drivers blend door actuator. Sounds like its stuck or broken. Does the temp display on the dash flash?
