Get your ac filter replaced. My car did the same thing for a year until I figured out what the problem was.

Needs to be recharged and you more than likely have a leak somewhere

the computer that controls the deflector motor are not responding and opening the door for heat, I'm sure you have climate control,check the temp setting sensor to the computer input first

Your issues can not be answered easily or definitively, as the LS is very complex and all electronic.
I would need the stored codes,that set the check light (MIL Light)
You can cycle the right dash display to ACFilter and Reset,with the top row of buttons,in center of dash. There is no sensor on the Cabin Filter. All the dash displays, are just reminders,you can set any way you want, % wise.
Possible issues--Fuses
-- Coolant control valve
--DATC module
You will need a really good Technician,not a general mechanic, to diagnose your problem
You need to put a professional scanner on it, to start any diagnostic work

there are many thing beside a fuse, it may be low on freon or a bad low preasure switch and more ,you are right to start withthe fuses, then have the freon checked to make sure there enough in the system,you may have a leak. the fuse is a 10 amp fuse and its located in the aux fuse box in location F1-O1, here a diagram to help you, this fuse box should be under the hood, sometimes they put them under the dash on the pass/side.hope this helps.
