Removing
1. Remove the ignition key from the ignition lock and turn off all electrical consumers.
2. Remove the additional luggage storage box from the instrument panel on the passenger side.
3. Remove the ventilation fan assembly (for details, see the relevant section in this chapter).
4. Carefully disconnect the wiring harness from the clamps (4), as shown in the figure below.
5. Disconnect the wiring harness connector from the servo motor (2), shown in the figure below.
6. Unscrew the fastening screws (3) And (5), shown in the figure below.
7. Pull out the holder (1) together with the servo motor as far forward as possible to disengage the gearing.
8. Press on the outer grips on the top of the holder (1) in the direction of the arrows, and then remove the holder together with the servo motor, as shown in the figure below.
9. Disconnect the servo motor from the holder. To do this, compress the tabs of the latches (arrows) outward while detaching the servo motor from the holder as shown in the figure below.
Installation
Note.
- As a spare part, the electric motor for the fresh air intake/recirculation damper servomotor is supplied installed in position «recycling».
- If necessary, connect voltage to the servo motor and set it to position «recycling».
1. Press and fix the servo motor in the holder.
2. Place it on the housing and, pressing, fix the holder assembly with the electric motor on the housing. The gears should not engage yet.
3. The following operations must be performed simultaneously:
Close the fresh air damper and hold it in this position.
Insert the servo motor so that the first tooth (A) gear wheel (2) servo motor entered between the first and second teeth of the gear segment (1) fresh air dampers as shown in the figure below.
Install the recirculation damper so that the alignment marks (arrows) on the gear (2) and toothed flap segment (3) match as shown in the figure below.
Move and install the servo motor into the housing completely.
4. Install and tighten the screws for the servomotor holder with a tightening torque of 1 Nm.
5. Connect the harness connector to the damper servo motor. Turn on the ignition and check the operation of the damper servo motor by pressing the button «recycling».
Note.
- Make sure that smooth adjustment of fresh air supply and interior air recirculation is possible.
- If the kinematics of the drive gears is broken, it is necessary to turn off the ignition, remove the servo motor assembly and repeat the installation operations.
