2013 Golf TDI with 160,000 km. The noise is most noticeable while I'm idling, but doesn't seem to go away while driving either. The humming stops maybe 5 seconds after I press the AC button to turn it off. What should I be looking for here?

Replace the ac filter if its been a while. Pull the blower and see if anything got sucked in. Check the blower for play while it's out.

2014 SW here that sat in CA for a while till I bought it. At some point on the way home I noticed a vibration when the fan was on that of course got worse on med and high. Found out how to pull the blower motor, very easy, only to find a good amount of dust/dirt had settled on just a few of the vanes. Cleaned that off, problem solved
