I just bought a 2020 Ram 1500 Big Horn and have a question about the defroster fan. I've noticed that once I'm about 10 to 15 minutes of run time, the sound of the defroster fan seems to change. It almost sounds like it isn't blowing as hard, but if I hold my hand over the vent it seems to be blowing the same volume of air. It just sounds different (a little more muted sounding).

Anyone else experience this? The truck is still under factory warranty. I want to make sure I take it in if it's an issue.

Does it have the auto climate control equipment group? Try changing from recirculate and back manually and see if this is the same change in fan noise you are hearing.
