A/C Air Distribution Housing Defroster Outlet Door

A/C Air Distribution Housing Defroster Outlet Door

• Beginning May 2007, a heater air distribution housing with a door - A - (in the air outlet to the defroster vents in the instrument panel) without a side cut-out - C - is gradually being installed. On vehicles without A/C, the change to the door has no influence on the heater control (the door is controlled only by adjusting the Climatronic control module (J255) ).






• Beginning May 2007, a A/C distribution housing with a door - A - (in the air outlet to the defroster vents in the instrument panel) without a side cut-out - C - is gradually being installed. With the introduction of the door with the side cut-out - C - the Climatronic control module (J255) is changed (the door must be opened further by the heater control due to the missing cut-out - B -, in order to direct the same amount of air to the windshield). Refer to the Electronic Parts Catalog (ETKA).

• The Climatronic control module, part number "8J0 820 043" through index "AA" may be installed only in vehicles which have an A/C air distribution housing with a door in the air outlet to the defroster vents in the instrument panel with a side cut-out - B - that has been or will be installed (exception: vehicles that will only be driven in tropical regions).

• On vehicles, which will be driven in tropical areas only, to prevent the windshield from fogging up on the outside in the area of the "Defrost" outlet, a door in the air outlet to the defroster vent in the instrument panel without a side cut-out - C - has already been installed since March 2007. Since, under these conditions (no winter operation) the windshield does not fog up from the inside, a Climatronic control module part number "8J0 820 043" through index "AA" can be installed in these vehicles.

• With the Climatronic control module part number "8J0 820 043" from index "AB" the "adaptation " function (in adaptation channel "30") the door - A - (in the air outlet for the defroster in the instrument panel) can be entered (Climatronic control module adapting) using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.
