The A/C and blower unit assembly uses three actuators
  • Blower unit
    1. Air intake actuator
  • A/C unit
    1. Air mode actuator
    2. Air mix actuator

The lower actuator on the A/C unit requires to be firstly removed from the A/C unit.

The removal procedure is the same for all three actuators.

To remove the blower unit actuator remove the A/C unit from the IP (Refer to 'A/C Unit', page 12-3-11).

Removal

  1. Remove the IP from the vehicle (Refer to 'Instrument Panel (IP) (01.12)', page 1-9-1).

To gain access to the Air mode and Air mix actuators remove the A/C control module (screws x3).

  1. Disconnect the actuator control rod.
