Fresh Air/Recirculating Air/Back Pressure Door Motor Adjuster, Removing And Installing: Installing
Install in reverse order of removal. Note the following:
- Tightening specification. Refer to OVERVIEW - HEATER AND A/C UNIT .
Check the function of the doors and linkage before installing.
Check if the lever and shafts are seated correctly in the mounts.
-- The actuator mount can only be installed in one position on the actuating arm -2-.
- The actuator mount must be opposite the actuating arm as shown in the illustration.
If the mount and the actuating arm are not opposite each other, turn the mount in the actuator. See notes. Refer to ACTUATOR .
-- Mount the actuator on the air distribution housing so that the actuating arm reaches into the mount -1- -arrow-.
- There must not be any play in the connection between the actuator and the actuating arm.
If the bolts cannot be installed, the actuator does not sit completely on the housing.
-- Install the wiring harness so that it cannot come in contact with any moving parts (for example, the lever on the actuator).
-- To check the actuator function, connect the adapter cable (refer to ACTUATOR ) or connect the actuator terminals "5" and "6" to a 12 V battery via a 5A fuse using a cable from the :VAG1594D .
Turn the actuator so far until it has reached a favorable position for installation. The direction of rotation can be reversed by switching the positive and negative.
-- When mounting the adjuster, the operating lever -3- must engage into back pressure door lever -2-.
-- Check the DTC memory and erase any displayed entries, then perform the "basic setting". Use the :Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
-- Check the heater and A/C unit function.
