Question: AC not working

Blows air at full force but temp remains consistent with outside air (like running the vent). Doesn't heat or cool. Prior to it "going out" I would hear an occasional buzz which I thought to be the AC unit...but I still get the same noise occasionally with the AC turned completely off. Also, the 2 driver side vents stop putting out cold air a week or so before the passenger side.

Maybe a failure of the HVAC control module, or separate failures of the AC and heater. Could be low on refrigerant and have a clogged heater core at the same time.

Take it in and have the problem properly diagnosed.
