I have an 2001 Grand Caravan 3.8L , The heater works on one side & cold air blows out the passenger side even though its set to high (hot) Is there a simple fix on the duel climate control to make it blow hot out the pass. side?

 

If everything else on the climate control system works properly, you can probably narrow the problem down to passenger zone control switch, passenger zone blend door actuator, and wiring between the two. The first thing I would do is look for more obvious things like loose or broken connections between control switch and actuator (remove and reinstall the connector plugs). Sometimes this alone will solve the problem. Then I would make sure the passenger zone blend door is not stuck and physically able to move. Then I would ensure there is proper continuity through the zone control switch and maybe jump some power directly to the actuator to ensure the actuator motor is functional. That would be my approach. Exact proceedure would probably vary depending what I found when I got in there.

 

Well thank you very much !! Good info....I do have one question, where is the pass. accuator assm. located?

 

Here is the TSB for it. takes half hr to 1 hr to do.
