Was it cold outside...and did things change after the engine warmed up? If yes, nothing is wrong...just the cold arrest feature that prevents the IHKA system from blowing cold air on the passengers.

Similar issue occurred with my 2003 540iA about a month ago and it was the FSU - there was no hot/cold air blowing regardless of the setting.

p.s. How's the weather up there as I'm a native Montrealer and will be heading up there to see my family in the next couple of weeks?

It was the setting in the MID for the onboard computer that had the vents switched off. Thanks again everybody for the help..

Hmm...that doesn't make sense because there is no setting in the OBC that would totally close the HVAC systems vents when the IHKA control panel is on.

It sounds like you are looking at one of the timer events that allows you to turn on or keep the blower running even if the engine is turned off and/or the keys are removed from the ignition...this feature is usually used in the summer to keep air circulating through the cabin to prevent the interior temps from getting to high as the car is locked up while parked and running errands.

The VENT ON feature can only be initiated with the ignition in KL R (ignition position 1)...and immediately turns the blower on and it will run up 30 minutes. I also use the feature on hot humid days/nights after using the AC & I'm parked in the garage or other dark location...this prevents the growth of mold & bacteria on the condensor by continuing to draw air across it I dread of letting it sit in a wet & dark environment which is like parking on lover's lane for mold/bacteria

The independent venting features gives you 3 settings...two are timed events (1TIMER2) & 1 immediate venting feature (VENT ON):


You probably have another issue...again if you are referring to the VENT ON/VENT OFF prompt you see on the left side of the MID when key is in KL R (only high MID or NAV screens have this feature)...if you have the LOW MID...you won't see this feature on your MID:
