Cold air on passenger side

[shogun]

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

Wish there was a way of installing the replacement arm without having to tear the dash apart

Ok so how did you do the zip tie repair? Hey my son just landed a 91 325i convertible, know anyone who knows how to modify the electric top to manual?

After 4 months of operation I can confirm that the zip tie solution on my car works like a charm, no modification required so far. So I leave it as it is now.

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.

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.
