Right Retaining Plate With Right Footwell Door Motor (V109) and Right Center Vent Motor (V111)
Right Retaining Plate with Right Footwell Door Motor (V109) and Right Center Vent Motor (V111)
• The mounting plate with the Right Footwell Door Motor and the Right Center Vent Motor is installed only on vehicles equipped with the "Comfort" A/C system.
• Right Footwell Door Motor mounting plate and Right Center Vent Motor disassembling and assembling, refer to => [ Right Retaining Plate with Right Footwell Door Motor (V109) and Right Center Vent Motor (V111) ] Right Retaining Plate With Right Footwell Door Motor (V109) and Right Center Vent Motor (V111).
• 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 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 passenger seats as far back as possible.
- Turn off the ignition.
- Remove the glove compartment.
- Remove bolts - A -.
- Loosen the air duct for the right instrument panel vent from the instrument panel crossmember, but do not remove it.
• The air guide from the air guide channel - B - is attached to the right instrument panel vent with two screws. To loosen, remove the screw which is installed at the bottom and is accessible.
- Remove the air guide channel - B - leading to the right instrument panel vent (passenger side).
- Remove the air intake housing. Refer to => [ A/C Unit Air Intake Housing ] A/C Unit Air Intake Housing.
- Mark the connector - A - (to the Right Center Vent Motor) and - B - (Right Footwell Door Motor) (to prevent confusion).
- Disconnect the connector - A - and - B -.
- Disconnect the connector from the Evaporator Vent Temperature Sensor (G263). Refer to => [ Evaporator Vent Temperature Sensor (G263) ] Evaporator Vent Temperature Sensor (G263).
- Loosen the wiring harness - D - from the mounting points on the mounting plate - J -.
- Carefully loosen the different connecting rods (from - E - to - H -) from each door.
• The connecting rods (from - E - through - H -) are clipped on to the levers; unclip them carefully so that the lever does not get damaged.
• Depending on the production date, there are different versions of the levers and connections on the A/C unit. Refer to => [ Air Conditioner, Levers and Connecting Elements ] Air Conditioner, Levers and Connecting Elements and the Electronic Parts Catalog (ETKA).
- Remove the screws - C -.
- Remove the mounting plate - J - (together with the control motors, the lever, the cam plate and the connector rods) from the A/C unit.
Installing
Installation is carried out in the reverse order while observing the following.
- Apply a small quantity of grease (G 000 150) to the cam plate guides as well as to the pins at the door levers. Refer to Electronic Parts Catalog (ETKA).
- Make sure the levers, cam plates and connector rod mounting plates - J - are assembled correctly. Refer to => [ Right Retaining Plate with Right Footwell Door Motor (V109) and Right Center Vent Motor (V111) ] Right Retaining Plate With Right Footwell Door Motor (V109) and Right Center Vent Motor (V111).
- When installing the mounting plate - J - pay attention to the lever pin - K - and the cam plate guide - L -.
• Make sure the curved washer stop - M - is inserted between both stops on the A/C - N - and - O - (the cam plate must be able to move across the range marked with the arrow).
- Install the screws - C -.
- Connect the connector - A - and - B - according to the markings.
- Mount the wiring harness - D - into the mounting points on the mounting plate - J -.
- Install the wiring harness - D - so that it cannot come in contact with any moving parts (such as the actuating arm).
- Install the removed parts in the opposite order
- 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".
- Switch on the ignition.
- Adjust and check the air flow direction on the different air ducts via Climatronic control module, if the quantity of air actually changes at each setting.
