Wife noticed that the AC was getting warmer and warmer?

About 3 weeks ago, my wife noticed that the AC was getting warmer and warmer over a span of three days before it completely went out. I came to the conclusion that the system was low on freon and I charged it. It seemed to do the trick but now I'm having a couple of issues:

1. Ice cold air only comes out on the passenger side and cabin vents
2. This air (passenger/cabin), does not change in temperature until temp setting is maxed out at 86 degrees
3. The air coming out on the drivers side is luke warm at idle and will cool down some during acceleration but will warm back up after being idle.
4. The drivers side air will not gradually get warmer (the same as passenger/cabin) as the temp control setting is increased but will become hot once maxed out at 86 degrees.

I looked at the actuator doors on both sides and they seem to be moving as I play around with increasing/decreasing the temperature control.

What am I missing?

Thanks
