Both Front and rear blower motor Removal on Chrysler Pacifica?

In this chapter details are provided for Front and Rear blower motor removal and installation details.

The Chrysler Pacifica Blower motor replacing details are as follows:----

Front

CAUTION

This vehicle is 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 or death.

NOTE

The blower motor is located on the passenger side of the vehicle under the instrument panel. The blower motor can be removed from the vehicle without having to remove the HVAC housing.

1. Disconnect and isolate the negative battery cable.
2. Remove the passenger side cowl trim panel, as follows:
   1. Remove instrument panel side cover.
   2. Remove front door sill scuff plate.
   3. Remove A-pillar cowl side trim panel from vehicle by disengaging hidden clips.
3. Position the carpet to access the front upper screw that secures the air inlet housing.
4. Remove the recirculation door actuator, as follows:
   1. Pull the carpet on the passenger side front floor away from the dash panel far enough to access the recirculation door actuator.
   2. Disconnect the HVAC wire harness connector from the recirculation door actuator.
   3. Remove the two screws that secure the recirculation door actuator to the air inlet housing and remove the actuator.

2. Disconnect the blower motor wire lead connector from the blower motor resistor or power module, depending on application.
3. Remove the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing.
4. Remove the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and the lower HVAC housing.
5. Push the rubber grommet through the opening in the lower air inlet housing.
6. Route the blower motor wire lead through the opening in the lower air inlet housing and remove the lower air inlet housing from the vehicle.
7. Position the recirculation-air door as necessary to access and remove the three screws that secure the blower motor to the lower half of the HVAC housing.

8. Gently flex the recirculation-air door downward to gain access to remove the blower motor from the HVAC housing.
   
   NOTE

   To aid in installation, note the position of the blower motor mounting tabs prior to removal.
9. Remove the blower motor from the HVAC housing by rotating and tilting the blower motor as necessary.

To install:

1. Gently flex the recirculation-air door downward to gain access to install the blower motor into the HVAC housing.
2. Position the blower motor to the HVAC housing and tilt and rotate the blower motor as necessary to install it into the HVAC housing.
3. Align the blower motor mounting tabs to the locations noted during removal and install the three screws that secure the blower motor to the HVAC housing. Tighten the screws to 17 inch lbs. (2 Nm).
4. Route the blower motor wire lead through the opening in the lower air inlet housing and seat the rubber grommet.
5. Position the recirculation door pivot shaft into the lower air inlet housing and install the inlet housing.
6. Install the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and the lower HVAC housing. Tighten the screws to 17 inch lbs. (2 Nm).
7. Install the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing. Tighten the screw to 17 inch lbs. (2 Nm).
8. Connect the blower motor wire lead connector to the blower motor resistor or power module, depending on application.
9. Install the recirculation door actuator.
10. Reposition the carpet.
11. Install the passenger side cowl trim panel.
12. Reconnect the negative battery cable.
13. Perform the heater-A/C control calibration procedure, as follows:
    
    NOTE

    The A/C-heater control module must be recalibrated each time an actuator motor or the A/C-heater control is replaced. If the vehicle is so equipped, the calibration procedure also includes rear HVAC positions for each actuator motor.
    
    
    1. Turn the ignition switch to the ON position.
    2. If equipped with the Manual Temperature Control (MTC) system, press and hold the Power and Recirculation buttons for at least five seconds. If equipped with the automatic temperature control (ATC) system, simultaneously press and hold the Power and Recirculation buttons on the A/C-heater control for at least five seconds. The MTC A/C-heater control Power button light emitting diode (LED) and Recirculation button LED, or the ATC A/C-heater control Delay and Recirculation graphics will begin to flash when the calibration procedure has begun.
    3. The calibration procedure should take less than two minutes to complete for the manual A/C-heater control, and less than twenty seconds for the ATC A/C-heater control. When the LEDs or graphics stop flashing, the calibration procedure is complete.
    4. If the LEDs or graphics continue to flash beyond the two minute (manual) or twenty second (ATC) calibration time, it indicates that the A/C-heater control has detected a failure and a Diagnostic Trouble Code (DTC) has been set. The LEDs or graphics will continue to flash even after the ignition switch is cycled Off and On, until a successful calibration is completed or until the vehicle has been driven about 8 miles (13 km).

Rear

NOTE

The rear blower motor and blower wheels are serviced only as a balanced unit. If either component is faulty or damaged, the entire blower motor and wheel assembly must be replaced.

1. Remove the front center floor console cover:
   1. Remove attaching screw(s) from the left and/or right console closeout panels.
   2. Remove center console closeout panel.
2. Disconnect and isolate the negative battery cable.
3. Disconnect the body wire harness connectors from the rear blower motor power module and the rear mode door actuator.

12. Perform the heater-A/C control calibration procedure, as follows: 
    
    NOTE

    The A/C-heater control module must be recalibrated each time an actuator motor or the A/C-heater control is replaced. If the vehicle is so equipped, the calibration procedure also includes rear HVAC positions for each actuator motor.
    
    
    1. Turn the ignition switch to the ON position.
    2. If equipped with the Manual Temperature Control (MTC) system, press and hold the Power and Recirculation buttons for at least five seconds. If equipped with the automatic temperature control (ATC) system, simultaneously press and hold the Power and Recirculation buttons on the A/C-heater control for at least five seconds. The MTC A/C-heater control Power button light emitting diode (LED) and Recirculation button LED, or the ATC A/C-heater control Delay and Recirculation graphics will begin to flash when the calibration procedure has begun.
    3. The calibration procedure should take less than two minutes to complete for the manual A/C-heater control, and less than twenty seconds for the ATC A/C-heater control. When the LEDs or graphics stop flashing, the calibration procedure is complete.
    4. If the LEDs or graphics continue to flash beyond the two minute (manual) or twenty second (ATC) calibration time, it indicates that the A/C-heater control has detected a failure and a Diagnostic Trouble Code (DTC) has been set. The LEDs or graphics will continue to flash even after the ignition switch is cycled Off and On, until a successful calibration is completed or until the vehicle has been driven about 8 miles (13 km).
