E32 - No air from vents

[SteveGoodie]

Hi there, I'm new to BMW ownership and (obviously) to this forum and could certainly use some guidance here. I have a 1991 E32 730i and my problem is that no matter what I do with the heater/blower/ac controls I can't get any air out of any of the vents.

I can hear the blower motor going and by the sound it makes it's blowing air (not just spinning on its own). Selecting the various push buttons on the control panel I can hear the stepper motors/flaps turning.

I've checked all the fuses under the bonnet and pulled/re-seated all the relays in the fuse box but nothing appears to make any difference.

Any and all suggestions would be much appreciated.

Regards
SteveGoodie

With tips from another forum I managed to track down my problem to the micro filter, which was replaced today. I now get plenty of air from all vents, although the filter didn't look too bad on first inspection.

Where is it located? Does the ac is cold enough (assuming is properly charged)?

Thanx!
