2010 GLK 350 Winter Heating Passenger Vent Soundds
With the cold weather outside, got the interior winter heat on blast but with a very annoying sound embedded in the video link.
Sound comes intermittently, and only when heat is set for windshield and/or upper passenger, but not for feet below.
Sounds like it's got something to do with the piping, but wondering if anyone else has experienced this same issue/noise? Recommend to go to a mechanic or can I tear it apart myself.
As always, grateful for all your assistance thanks!
