Today, about 85*F outside, I put in Auto and set to 65* even for passenger. But no air at all coming from any vents, I see 3 bars though. I even hit the "max Cool" button, I can hear a lot of wind noise, but no air going out at all. It looks like something is block the air to come out.

anyone have this problem before? I searched this forum and it seems like I am only the unlucky one. help...

this may sound stupid, but did you check to make sure your vents were open?

[nhhiep]

yes, they were all open. I have this car for 4 months already in hot weather and have been using it up to now with no problem. Just now, it's acting up.

Same problem? Were you driving a long time? There have been other posts about screwy A/C that are similar to the one I linked.

hmm, that is weird, if you hear your fan going but not feeling it, must be some sorta blockage

See if air is coming out on the windscreen vents by your center speaker (if you have Logic7). If it is, then the vent motor may be failing. Ever since the E46, every time you switch off your car the system directs all air to the windscreen so if the system fails when you next start the car you will at least be able to demist the screen.

...so that's why we can hear the vent motor re-directing the airflow towards the occupants again, once the car is switched back on!

Thanks for that Jay.

This explains SO many things. I always wondered what the "rattling" around in the dash was if you climb into your parked car and just sit quiet and listen for a minute. It also explains why it takes several seconds for the air to come out of the main vents after start-up, unlike other cars where the air starts blowing immediately. Good information, thanks!

No problem!
Also, once every ten engine stops the system will perform a full test of its ventilation system by moving the motors to the full extremes of their range.
