No air through floor vents

2015 XC60, Drive E, T5.

I just noticed I am not getting any air through the floor vents. Blower blows air through dash and window defroster as normal. When the floor is selected is continues to blow from the dash vents.

Any ideas on what to look for?

bump,

does anyone know if the check gates are controlled via vacuum or electric motor?

Probably one of the damper motors, and they are electric. It should throw an error code, and VIDA also has a way to test and recalibrate the motor(s). (TBH, I haven't done it on any of my 2012s, but I replaced two motors on the '99 S70 on separate occasions.)

Motors are not cheap, so I wouldn't start replacing until you throw a computer on it. But you should be under warranty still, right?

Unfortunately no warranty. 60k on the odometer. I have to bring it to the dealer for an intermittent idle issue that I can't figure out.

I had to replace the oil trap at 57k because of a high idle and whistle sound. After replacing it, from time to time the idle will jump up and cause CEL to throw P0507 (idle higher than expected). The CEL will turn off on it's own. I am thinking it's a vacuum issue but haven't located the cause.

I will get an estimate to repair the floor vent. Hopefully it is just a flash of the computer or something simple. My dealer offers free software updates when you bring it in for service.

Thank you for the link.
