| Type |
The air recirculation flap has a DC motor. The ACC unit reverses output polarity in order to change the direction of motor rotation.
| Connection |
ACC
The motor is connected to ACC unit pins 25 (K42) and 4 (K42). The output polarity is reversed in order to change motor rotation direction. The ACC unit applies a B+ feed on pin 25 and grounds pin 4 in order to operate the motor for fresh air setting and conversely in order to operate the motor for cabin air retrieval.
