fixing broken vent stepper motors

E36 325i convertible for your son? Congratulations. I also have an E36 M3, 1998 model. Love it.

For conversion of electric top to manual you might ask on BF E36 section, there is especially one expert called flyfishvt, he owns a 97 328i Vert and knows this best.

as I had a similar problem with no air from vents, I investigated further on my car and we found no broken stepper motor mount, but the stepper motor did not hold in place with the clips, so we fixed it with zip tie, works like a charm now. Have made a youtube on my spare IHKA unit to show how the flaps work

Update: 3 years later the zip tie repair on my stepper motor bracket still works perfect. Advantage is that not many parts have to be removed to repair this. Just the radio came out and some covers outside center console next to the aircon unit and the cover under steering wheel, and one needs slim and flexible fingers to reach the stepper motor then.

Temporary zip tie fix still works, but next time I am in there I will make a solid metal bracket for the stepper motors on each side.
