SOURCE: The HVAC does not switch

The location of the blend motor on my 2005 malibu is on the driver side, near the center consol, not easy to get to. Before you try to remove the blend motor, unplug the wires it, turn the temp knob to cool side, disconnect the pos side of the battery for a couple of minutes. Reconnect the battery, plug in the bend motor start the car and turn the temp control to heat side. If this does not work remove the motor and repeat. the motor my be jamed. I had the same problem, this might be a cheaper way to fix this instead of the dealer. PS if you remove the blend motor, be carfull to look at the orientation of the spring on the shaft of the door in case it pops off.

Your heating and air conditioning system is controlled by the Body Control Module (BCM). Any diagnosis should begin with scanning the (BCM) for trouble codes to determine the source of the problem and/or which circuits and components are involved.

If a failed mode door actuator is, in fact the problem, the instrument panel must be removed to gain access to it.

Blend door mixes hot and cold, not a distribution control. Look for loose or dislodged vac lines... Heater designed to fail in defrost mode.

NOTE: LHD model shown. RHD model similar. All vehicles are equipped with a common heater, ventilation and air conditioning (HVAC) housing assembly (1). The heating-A/C system combines A/C, heating, and ventilating capabilities in a single HVAC housing mounted within the passenger compartment behind the instrument panel. The HVAC housing assembly includes:
  1. Mode-air doors (2)
  2. A/C evaporator (3)
  3. Recirculation door actuator (4)
  4. Air inlet housing (5)

Need info on heater mode door operation


The mode door actuators are reversible, 12-volt direct current (DC) servo motors. The heating-A/C systems on this vehicle use two mode door actuators. One for the panel/floor-air door and one for the defrost-air door.

Both the defrost door actuator (1) and the panel/floor door actuator (2) and the are located on the driver side end of the HVAC housing (3), close to the dash panel.


All actuators (1) are interchangeable with each other. Each actuator is contained within an identical black molded plastic housing with an integral wire connector receptacle (2). Each actuator also has an identical output shaft with splines (3) that connects it to its respective door linkage and three integral mounting tabs (4) that allow the actuator to be secured to the HVAC housing. The mode door actuators do not require mechanical indexing to the mode-air doors, as they are electronically calibrated by the A/C-heater control.
OPERATION

The mode door actuators are connected to the A/C-heater control through the vehicle electrical system by dedicated two-wire leads and connectors of the HVAC wire harness. The mode door actuators can move the defrost-air door and the panel/floor-air door in two directions. When the A/C-heater control pulls the voltage on one side of the motor connection high and the other connection low, the mode-air door will move in one direction. When the A/C-heater control reverses the polarity of the voltage to the motor, the mode-air door moves in the opposite direction.

When the A/C-heater control makes the voltage to both connections high or both connections low, the mode-air door stops and will not move. The A/C-heater control uses a pulse-count positioning system to monitor the operation and relative position of the mode door actuators and the mode-air doors. The A/C-heater control learns the mode-air door stop positions during the Actuator Calibration procedure and will store a Diagnostic Trouble Code (DTC) for any problems it detects in the mode door actuator circuits.

The mode door actuators are diagnosed using a scan tool (Refer to 28 - DTC-Based Diagnostics/HVAC - Diagnosis and Testing).

The mode door actuators cannot be adjusted or repaired and must be replaced if inoperative or damaged.

Check to see if actuator is moving,where the actuator plugs in the door the plastic may have broken on the door then the heater box would need to come out to repair but if the actuator isn't working then easily replaced then all doors recalibrated provided it's getting the command from HVAC module..

02 dodge ram 1500 heat on passenger side of vechile only


If you are getting heat only on the pass. side then I believe the blend door has failed. Dodge has a fix and the job is not easy as almost the whole dash needs to come out in order to get to the heater box and the door. I have read that a simple flush of the heater core will cure it, But that diidn't work for me. I think because dual climate control was an option the door is set up to control the two sides of the cab. When it fails only the pass. side gets heat.

Unfortunatly you do have to remove the dash to access any of the blend door or fresh air door actuators
here is a step by step proceedure this takes aprox 5 hrs in a shop so plan on a weekend at home good luck

FLOOR - DEFROST DOOR ACTUATOR

REMOVAL

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

Disconnect and isolate the battery negative cable.
Remove the instrument panel assembly from the vehicle.

zjlimited_318.jpg

Fig. HVAC housing, dual zone shown (single zone similar)-nut (1), passenger blend door actuator (2), nut (3), inlet baffle (4), recirc door actuator (5), recirc air door (6), driver side blend door actuator (7), HVAC housing (8), bolt (9), defroster door actuator (10), mode door actuator (11)

Remove the electrical connector from the actuator.
Remove the mounting screws from the actuator.
Remove the actuator from the HVAC housing.

INSTALLATION
Install the floor-defrost door actuator to the HVAC assembly.
Install the mounting screws and tighten to 2.2 Nm (20 in. lbs.) .
Install the actuator electrical connector.
Install the instrument panel assembly into the vehicle.
Connect the battery negative cable.

I suggest check (or replace if is necessary), the blend door it is a huge project you have to remove the dash board. There is a repair kit available either way it is a 8 hr shop time project.

Hope helps.

I changed the battery on 2006 Trailblazer SS. Now I can only get AC from my windshield and floor vents. Nothing from the dash vents. Also the temp control only gives coldest temp. I have checked fuses...


once you disconnect the battery your body control module loses power and memory you have to get some one with a scanner with reprogramming capabilities and have the computers reset ,dealer?
