Question about 2003 Dodge Caravan
I have just fixed this same problem on my 2001 Dodge GC Sport. First thing you can do without any tools is a self-diagnostic check of the system. Turn on the ignition and hold the Recirculation and Power buttons at the same time for 5 seconds. All of the lights on the panel should flash as it begins to check the actuators. This test takes a couple of minutes to complete. If the light on the Recirculation button is flashing after completion then one of the actuators is faulty. This same procedure is used for calibration. The faulty actuator is very easy to get to and is located on the driver's side above the gas pedal. You will have to remove a couple of panels to get to it, but there are only a few screws that hold these panels on. Once the panels are removed you will notice 3 actuator motors, the one that controls the passenger side temperature is the one closest to the firewall or engine compartment. Once I removed the actuator I discovered the plastic shaft that turns the metal rod to the passenger side blend door was broken. This is dealership only part and if you call them and ask them over the phone they will tell you they only sell the whole actuator which is a $194. What you need to do is reference TSB #24-006-01 and Part #04885511AA and it will cost you $5. Here is the link http://ww2.justanswer.com/uploads/dodgetech2875/2009-11-12_061522_heater.pdf.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

It sounds like your electronic vent actuator has gone bad, it's common to go bad and may need to be replaced. There are tinny gears that wear out and the vent actuator stops working. You can try this, turn the radio off first so you don't have to enter the reset code to activate your radio. Disconnect the battery for 30 seconds and reconnect it, if the actuator has lost it's base line and stuck in the open heat position, this will reset it, just make sure the setting is to cold and off before disconnecting and reconnecting the battery. If this does not work, then it's a bad actuator and Auto Zone should have the part you need and will have the step by step instructions for you to the job you self, I believe the dealer is a $415,00 repair cost for this. Good luck and keep me posted.

You need to replace the drivers side temp actuator that is located on the left side of the HVAC box. It is retained by 3 screws and is fairly easy to replace.

GM has a known problem with the electric actuators that operate the blend and temperature doors in the HVAC system. There are 4 or 5 of these in the typical system. Any can start sticking or binding and cause this problem. Sometimes they can be cleaned, or they might need to be replaced. Sometimes resetting the HVAC system controller by disconnecting the battery for 10 minutes, then reconnecting it, will correct the problem.
