If air flow flap control motor -V71- cannot be fitted to shaft of fresh air and air recirculation flap -1-, remove fresh air blower -V2-, → Chapter, and position flap by hand. Pull connector -1- off air flow flap control motor -V71-2-.Īttach air flow flap control motor -V71- to shaft for fresh air and air recirculation flap -1. Press fresh air and air recirculation button. Push connector -1- onto air flow flap control motor -V71-2. To ease the installation of the control motor, perform the following work before installing: Lower control motor and simultaneously pull from shaft for fresh air and air recirculation flap -2-, -arrow A-.Ī new air flow flap control motor -V71- is supplied in the “air recirculation” position. The air flow flap control motor -V71- must be guided into the distribution box and evaporator housing. Note The air flow flap control motor also operates the fresh air and air recirculation flap.Ĭarefully unclip air flow flap operating rod -1- from lever -2- using a screwdriver. ![]()
