Driver side blowing hot air passenger side blowing cold air


I'm having the same problem except on mine it's the driver's side that's blowing cold. Do you have the pictures in a finer resolution? I can't make them out and when I zoom, they are too grainy. Does the replacement require removing the dashboard? What's the general cost of the acuators? Are they readily available at like NAPA or other parts stores?

Problem with dual zone heating only one side i check control thermost botton is ok


Sounds like the blend door actuator. It separates the driver and passenger side from getting air on the AZC system. Here are some instructions on replacing it:
The passenger side blend door actuator is used on all models equipped with Automatic Zone Control (AZC). This actuator is located on the front of the HVAC housing to the right of the floor panel transmission tunnel and cannot be removed from the passenger compartment without instrument panel or HVAC housing removal.

NOTE: This procedure is for AZC Systems (Passenger side only).

  1. Disconnect and isolate the battery negative cable.
  2. Remove the glove box door. See: Body and Frame\Interior Moulding / Trim
  3. Remove the lower I/P glove box door surround panel.
  4. Remove the dash assembly. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
  5. Remove the HVAC assembly. See: Housing Assembly HVAC\Service and Repair
  6. Unplug the wire harness connector from the blend door actuator.
  7. Remove the 2 screws that secure the blend door actuator to the HVAC housing.
  8. Remove the blend door actuator from the HVAC housing.
INSTALLATION - AZC (Passenger side only)


  1. In stall the blend door actuator on the HVAC housing and tighten the two mounting screws to 2.2 Nm (20 in. lbs.).
  2. Plug in the wire harness connector to the blend door actuator.
  3. In stall the HVAC unit into the vehicle. See: Housing Assembly HVAC\Service and Repair
  4. Install the instrument panel assembly into the vehicle. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
  5. Evacuate the HVAC system.
  6. Recharge the HVAC system.
  7. Connect and the battery negative cable.
Hope it helps! If you need more, just send me an email at familyguy77351 at yah I wil be glad to finish helping you with more detail.

Afternnon, just wondering about the best way to locate the blend doors in the hvac box without ripping out the dash on my 2000 jeep grand cherokee. Thanks in advance. Duane


y9ou can gain access to the driver side blend door actuator by removing the glove box. The actuator will be in the left corner of the glove box opening. If you remove the actuator you will be able to turn the pin. If you can turn it 360 degrees the blend door is broke.

If your lucky its only the drivers side. If you get the repair kit from chrysler it will come with instructions with pictures on how to replace the blend door without pulling the HVAC unit/Dash. If the passenger side is broken the HVAC unit will need to be removed.

Heater treater (google them) also have a metal blend door replacement and instructions online on how to replace them without pulling the HVAC housing.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Hot air comes out the passenger side when air condirioning is on.


The control module or actuator is most likely the cause. You can manually set it for cold air until winter. Actuator is under the dash right by the blower.
