The system is equipped with stepper motors (4 motors for '97 models and 6 motors for '98 on) that control air distribution flaps. The motors are controlled by the IHKA Control module via the M-Bus. All of the motor processors receive the same signal but only the addressed motor will respond and move to the desired position. Drives: 2008 E90 AW 328i N51. Join Date: Oct 2009.

Can't find any other blown fuse but only looked in the cargo area and glove box. Fuse 31, 48 and 44 are all good.
