Three so-called Bowden cables run from there to the duct housing, often referred to as «air duct». Air valves are located in this housing, directing the air flow in the right direction.
Replacing cable drives
Removal and installation are the same for almost all cable drives.
Take off the radio.
If necessary, remove the center console storage box (see chapter «Salon»).
Now you can pull out the control unit for heating and ventilation of the passenger compartment a little from the dashboard, just enough to reach the Bowden cable mounts.
Use a screwdriver to pry the drive cable lock out of the latch on the drive unit.
Left: dust filter (1) fixed with two lock nuts (arrows) on the fan housing.
Right: air nozzle removed (1) in the middle of the dashboard. Both spring brackets are very clearly visible (arrow), with which the nozzle is held in the recess for it.
Cable for adjusting the amount of incoming air. Withdrawal:
Left: The system shows the rope with its loop (1) on the system lever. Rope sheath (3) rests on a support (2), which is installed in the control system. If the latch breaks during removal, the support can be strengthened with a self-tapping screw for metal.
Right: rope sheath (1) ends in front of the air damper of the support. The rope itself (2) attached to the choke lever.
The end of the cable is bent into a loop and loosely inserted into the drive arm.
On the air duct box, the shells of the Bowden cables are rigidly screwed to the lugs or fixed with plastic latches.
Loosen the screws or squeeze the latches and remove the clips.
