Early Bronco

Just picked up a new to me ‘25 BS Badlands w/Sasquatch and Badlands tech package, 6k miles. Didn’t realize during the test drive but driving around today the interior fan for the heating system has a constant buzz/whine/noise that increases/decreases frequency as you adjust the speed. Even on low speed it’s a constant noise… anyone have this going on?
