AC issues

The AC stopped working (in the middle of summer, of course). When I turn the AC on the compressor clutch tries to engage but stops. The relay looks like it is working properly and the system is charged.

I had recently replaced a fuse that was disengaging occasionally, which was causing the driver side portion of the dual zone to stop running AC (would start blowing engine temperature air).

After the AC quit I also noticed that the zone control knob was not working either. No matter which direction I switch it to it always stays on the torso setting for blowing air.

Any thoughts?
Thanks!
