Defroster Door Motor (V107)

Defroster Door Motor (V107)

• Currently in this vehicle, all motors are identical in construction. During the basic setting, the control motors are assigned and adapted corresponding to the switching sequence of the wiring. If this sequence does not conform with the specification, the control motors will adapt incorrectly and the door control will be wrong. Refer to => [ A/C Control Motor Block Diagram ] A/C Control Motor Block Diagram.

Removing

- Move the driver seat as far back as possible.

- Turn off the ignition.

- Remove the storage compartment under the dash panel on the driver's side.

- Remove the left footwell vent (driver side). Refer to => [ Left Footwell Vents ] Left Footwell Vents.

- Remove the accelerator pedal module.

- Mark the connector - D - if necessary (to rule out an interchange in the event several connectors are disconnected at the same time).






- Disconnect the connector - D -.

- Remove the screws - C -.

• To remove the screw - C - use ratchet wrench (T40083).

- Loosen the shaft - A - (on the motor - B -) from the actuating arm - E - and remove the motor.

Installing

Installation is carried out in the reverse order while observing the following.

- Check the position of the actuating arm - E - in the A/C guide - F - ; when doing this, pay attention to both stops - G -.

- Insert the shaft - A - (on the motor - B -) into the actuating arm - E -.

• The control motor does not have a stop; therefore the shaft - A - can be inserted into the actuating arm - E - in any position.

- Install the screws - C -.

- Connect the connector - D -.

- Install the wiring harness so that it cannot come in contact with any moving parts (such as the actuating arm).

- Install the removed parts in the opposite order.

- Switch on the ignition.

- Perform a basic setting and the output Diagnostic Test Mode (DTM) on the A/C system using the Vehicle diagnostic tester in "Guided Fault Finding".

• On this vehicle, the control motors are equipped with electronics. During the first basic setting, a new control motor learns its position on the air conditioner and can then be controlled by the Climatronic Control Module (J255) (currently all control motors are identical). Refer to the Vehicle diagnostic tester in "Guided Fault Finding"

• During the basic setting, the control motors are assigned and adapted corresponding to the switching sequence of the wiring. If this sequence does not conform the specification, the control motors will adapt incorrectly and the door control will be wrong. Refer to => [ A/C Control Motor Block Diagram ] A/C Control Motor Block Diagram.

- Check the Climatronic Control Module DTC memory and erase any displayed malfunction if necessary using the Vehicle diagnostic tester in "Guided Fault Finding".
