Rear Passenger Center Vent Not Blowing Anything in My 528i Good day. I have a 2000 528i sedan. The rear center vent doesn't blow any air. I had a 2001 X5 and seem to recall having the same system (though I won't swear to it) and think it worked. Just bought this vehicle from a friend and he doesn't recall if it ever worked or not for him

I think this could be a stuck blend valve, where it pulls 100% air through the heater core or the HVAC control has broken and gone insane. The system does seem to read the external temperature correctly.
twh said: +1 on don't pay attention to the AUC sensor. That's AUC sensor can activate activate recirculation mode under certain conditions -- for example, if it detects a lot of diesel exhaust. My 2006 530xi A/C quit blowing cold last summer. I've had the car since new and this was the first problem with the A/C.7QHV.
