Could also be a malfunctioning blend door.

Reread the OP, he said he had it worked on last year. It worked 6 days earlier but today it doesn't.

He did not say he had it fixed 6 days ago.

Possible issues:
Major system leak
Failed compressor
Failed compressor clutch
Failed compressor clutch wiring
Tossed fan belt (Selected vehicle only. My car did this, I also lost power steering, but the Alternator and water pump kept working, on my motor home there is but one belt)

Failed WATER VALVE (heater control valve).. That's one many overlook.

I had a compressor leak, replaced the compressor and all was great.

Ohm I also had a wire fault.. Never did find it, just replaced the wire.

6 days I,d bet breakfast you have a leak.call your tech back. leaks are hard to find.

Make sure compressor fuse is good..make sure that the fan at the condenser, yet another fuse is also running when you turn AC on..(it is behind one of the rear doors you get at with the soda machine key), also the temp control uses vacuum electric...make sure that is OK and lever is at cold ....make sure compressor didn't lose a belt on the engine (sep belt)...and turns on when AC is on...last is some kind of slow leak....

what am I missing....

I would guess refrigerant, due to a leak. Though it could be a control problem.
