Fresh Air/Recirculating Air/Back Pressure Door 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 align with the actuating arm as shown.
If the mount and the actuating arm do not align, turn the mount in the actuator. See notes. Refer to ACTUATOR INFORMATION .
-- Mount the actuator on the air distribution housing. While doing so, the actuating arm must engage 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.
-- Route the wiring harness so that it cannot come in contact with any moving parts (for example, the actuator lever).
-- To check the actuator function, connect the adapter cable or connect the actuator contacts "5" and "6" to a 12 V battery via a 5A fuse using a cable from the Connector Test Set :VAG1594D . Refer to ACTUATOR INFORMATION .
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 the back pressure door lever -2-.
-- Install the remaining components.
-- 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 heating and A/C system function.
