2018 Toyota Land Cruiser rear a/c

[Elliottgage21209]

I have a 2018 LC 200 and recently I noticed the vent that pulls air into the a/c system is louder than normal. Also there is a very small amount of air coming out of the vents in the headliner. I feel like something is clogged but not sure how to diagnose the issue. I have not taken it to the shop yet wanted to see if I could fix the issue.
Thank you!

Check the cabin air filter

rear unit finger guard or maybe the evaporator clogged with dog hair or monkey hair or whatever you have been hauling around. Usually you can pull off a big body panel in the rear and at least reach around the blower inlet finger guard mesh to see if it's getting blocked. The air inlet is usually outboard (you have to reach around) they are quieter that way.
