Loud HVAC fan in dash (6 Viewers)

[2014 LEX 570 GA]

Recently replaced the cabin air filter.

2x checked to make sure I did it correctly.

HVAC fan in dash now making a loud humming noise when AC is on max.

Anyone know what my issue is?

You can drop the squirrel cage fan out the bottom to see if something is stuck in it. Or if it needs changing due to a bad bushing or something, same process.

Just do your research.. I seem to remember someone here had issues with an aftermarket fan bolting in but the wiring being different..

Probably have something in the fan.

Although mine is “loud” occasionally and it has nothing in it mine has 300k on it so I’ll order one from Toyota one day.

Probably a leaf or other debris. Drop the fan and clean it out.
