About 3-4 months ago the regular air vents stopped blowing air randomly. Sometimes they blow, sometimes they don't
I noticed that they all work normally when I press the recirculation button, but when I turn off the recirculation button the fan is blowing the air even on high setting, but it sounds like it's blowing behind the center console, I can hear a vortex or something, but nothing is coming out of the vents

I connected VCDS and I see the following error codes:
Motor for Right Temperature Flap - Mechanical Failure
Motor for Fresh Air / Recirculated Air Flap - Mechanical Failure
Motor for Right Side Vent Flap - Mechanical Failure

See the screenshot attached.

I'm not sure if this is one part that has failed or multiple parts? Any idea how hard the DIY fix is for this?
