Hi everyone, my A/C is not blowing air even when turned up to the highest setting. It does blow air on the passenger side, but not on the drivers side. I’ve been hearing a weird vibrating kind of noise when the A/C is on, but it’d still work and blow air up until today. Anyone know what might be going on? I have a 2010 Malibu LTZ

If air is moving but only on one side, and since neither your model nor mine (2011 LTZ) came with dual-zone HVAC, you may have a hose that has come loose or a blend door that has failed.

You may also have some kind of debris in the system, but that's doubtful.
