hi all! (first post noob here)

i had the same probs - head unit ok, ability to change speeds, blower worked, but air only came out of the floor vent.

that diy Montanvs posted was awesome and i changed the fsu w/ part # 64 11 6 923 204 -- but it did not fix my problem. air still only comes out of the floor vent. from what i understand, that may be the wrong part for the e36 and it's for e39 and e46. so, i'm going to change it out to #64-11-9-929-540 (supposedly the correct part for e36's?).

i don't know, but if the other fsu doesn't fix the prob, i'm going to need some help as i'm trying to avoid going to the dealership unless i really have to.

not to sound obvious, but the button for directing air to the floor is off right? the "Auto" Button should be lit if this is a 96+ car

it's a 98 e36.

actually, the bottom vent blows air regardless of which button is lit (up, down, sideways, or auto). when i hit the a/c button, bottom vent shuts off so no air coming out of any vents, but i can still hear the blower and air flow rate is still controllable.

sounds like the "door" that controls the airflow is broke

also....not sure or not, but I think tha a/c only runs through the deforster vent and front vents. I'm going to have to test this on my way home tonight

FIY after changing the Final Stage Unit, it fixed my intermittent air flow problem. Climate Control works like a charm again.

Thanks for the link the FSU swap guys.

Iíll share my experience only because my symptoms were a little different than everyone elseís.

Purchased my í97 M3 sedan recetnly, all the climate controls seemed to function, setting would change, fan speed indicator etc, except for the fan would only barely blow air, regardless of the fan speed setting.
First step in the fan speed was slow, (seemed correct). Next faster fan speed was barely any more air flow, (seemed a little sluggish), increasing the fan speed beyond this point yielded no more air flow, no more fan speed (could just hear the fan with the engine off). I took a gamble on the issue being the Final Stage Unit ad replaced it per this thread. Purchased mine from Pelican for $43 plus shipping. Arrived today, had it swapped out in approx 15-17 minutes time, works perfectly now.

Thank you to all that contributed in this thread.

Paul

Hey guys,

Can you tell me why it was just a tightening of the torx screws that fixed the problem? I don't see how those would change the functioning of the FSU... I replaced my FSU today with a brand new one (the FSU in my E36 was replaced about 4 months ago and the AC was working fine). The FSU I took out looked almost new, but I tried the one I just bought anyhow. No luck - no blower. The blower is now extremely random. Sometimes it works, then I shut the car off and next time it doesn't.

Any ideas?

My next step might be seeing what's going on with the motor itself...

Thanks!
Steve

I have the exact same problem with my 97 M3 evo...

Have you been able to fix this with a new final stage resistor???
Its driving me insane, not being able to have air through the vents!

Add me to the long list of folks this thread has helped! The other day my climate control fan stopped working and then magically resumed functioning later in the day. I just used that DIY link and found that one of the Torx 20 screws had come a little loose. I hope that's the end of that issue!

Thanks,
