No Air from any vents

I have a new problem with my 2012 WK2. The fan is running and you can hear it change speeds with different switch speed settings, but no air is coming out any of the vents in any of the positions (defrost, floor, a/c vents). Tried different settings hot/cold, auto/manual but no difference.
I've read a few posts about blend door & recirc door problems but this seems different. The only think I could find similar was on an older WK thread about one of the doors failing and totally blocking the air from the fan.
Anyone else experienced this? Unfortunately my wife is driving the WK2 to Iowa today from Colorado so I'm going to be troubleshooting this remotely.
Thanks!

Try changing the cab filter. It may be clogged if it's never been changed.

I'm not saying this couldn't be it, but highly unlikely. It would have to crazy clogged and there are several older vehicles on the road in which the filter has never been changed.

Re: No Air from any vents

I had a similar issue a while back with my AC. I'm not sure it it is related but since I have changed my broken blend door gear, it has not reoccurred

Re: No Air from any vents

This happened to me today. My dad had the temp on 70 and I had mine on low suddenly no air would flow. I pulled over and restarted the vehicle and it came back like normal but I would like to know if this is a sign that the blend door gear is starting to fail.

Re: No Air from any vents

Hi folks, new member here. I know this post is old but I wanted to post a response in case other people stumbled upon it during their Google searching (which is what got me here)

I had the same exact problem as the original member above: one day my wife started complaining that although the blower motor worked on all speeds, and on all settings, hardly any air was coming through any of the vents!

I was puzzled.. first I thought it was a 'actuator' or maybe one of the 'blend doors'...NOPE

So it turns out, the in-cabin filter (behind glove box) was wet, soaked with water! She mentioned she had hit a giant puddle a day or 2 before. The water splashed upward from the puddle must have been sucked into the HVAC intake at the bottom of the windshield and hence soaked the in cabin filter!!

Apparently a soaking wet in cabin filter will prevent proper air flow in the HVAC system.

I replaced the in cabin filter with a new one and problem was instantly fixed! I hope this helps anyone else out there with the same problem.
