No air passenger side

[LC2008]

I have a 2008 200 series, I'm getting no air flow on the passenger side. No hot, cold, top, bottom air flow. Driver side works fine. I've read through other people's HVAC issues but I didn't see anything that matched mine. Wondering if anybody had this problem. Trying to avoid taking the dash apart, well, taking it apart isnt a problem, anyways, hoping theres a simple solution. Thanks

In your HVAC post reading, you likely found references to the goofy problems that can be caused by issues with the cabin filter and the recirculating/fresh change door. Put the HVAC system into recirculate, access the cabin filter, and make sure it’s seated properly and the recirc/fresh change door operates correctly.

Today it's semi working, it'll divert the air top to bottom, but slowly, and doesn't completely divert, there's always air coming out of top and bottom.
The recirc/fresh air door is working properly.

There are threads on here about resetting the motors (servos) that control air flow. Sometimes needed after a battery disconnect. There is also a technical service bulletin about resetting that covers some years.

I did the push the front rear defrost at the same time half a dozen times, gave up, came out the next morning and its now working fine. Thanks Sandroad.
