    the actuators are electrically controled. Is there any suggestions on how to reset/re-calabration of the hvac. My Chrysler van had a similar problem last year and there was a simple re-calabration that reset all the stop points.

On most cars when you push a button or slide a lever to change your choice of location where you want the air to blow out louvers move inside the dash to redirect the air to your chosen location. When you switch from heat to AC other louvers move. These louvers are often powered by vacuum lines running from the engine. If one of these louvers is stuck or if you have a vacuum leak in one of the lines it may be causing your problem.

If your sure you're looking at the right motor, Then the door is broke. Dash and plenum have to come out to fix it. Not a cheap fix.

Air conditioning system, when you turn on the air conditioner the drivers side blows cold air and the passengers side blows hot air? What causes this problem?


The most common cause of this is that you have a stuck air temperature control blend door, this can be a motor actuator issue or a jammed door or both (common). To replace both parts you will need to completely remove the dash from the car to access the blend door.

from what I've read repair involves removing the dashboard.
there are 2 sets of temp regulators and 2 air flow directors.
both sides have their own.

2007 chrysler town and country a/c blows cold through floor and defrost vent but not dash vents


Often a sign of a blend door problem. The blend door or doors are in the heater a/c box behind the dash.

Blows cold out of left defroster and hot air out of right


There are small doors within the heater/AC components located under the dash that direct the flow of air. Something has gone wrong with the operation of these doors.

I doubt this is a do-it-yourself project. Significant disassembly is required.

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.

A/c problem


You either have a bad control, or motor running the air direction door in the front HVAC unit, or a door that is stuck.

The front and rear units are totally separate.

The door directs where the air, cold or hot, should come out, whether it is panel vents, floor, defrost, or any combination of those.

This door and motor are located inside the heater box which usually requires a lot of the vehicle dash assembly to be taken apart to get to these parts.
