The compressor works but i get no air just hot air
It will need service,
check pressures.
hot air as in heater on, so turn off the heater,
test in pure A/C mode Cold.
when both A/C and heat are on this is called defrost mode
which adds cold dry air to hot air and dehumidifes the hot air and window.

good news is it can be changed with no tools in about 2 minutes. just take out the glove box and the cover comes off easy.

Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.
SOURCE: 2001 Suzuki XL-7. Heater blows hot one side, cold the other.
No ductwork [to the lower vents] under the dash. They are part of the heater core / blower housing is integrated (all one piece).
After reviewing shop manual, we suspect that one of the three damper flaps is not positioning correctly; or debris has blocked one side (which makes more sense given the symptoms).
We're waiting for the temperatures to get back in the plus numbers to check out the physical arrangement.

there is a point in operating temperature where the engine computer will cut the a/c compressor clutch to assist in avoiding overheating. When you go through another key cycle,this computer re-evaluates the temperature and allows a/c clutch operation once again if temperature is within operating range

Lots of possibilities. The first thing I would do is to have someone turn it on and off, while you look around under the hood (carefully, because fans go on and off).
The first thing you want to see, is if the AC compressor clutch is turning on and off properly. When the fan clutch is off, the outside of the pully will spin with the belt, but the inside will be standing still. When it is on, the whole pulley turns. If this does not work, then it could be a fuse, switch, or the clutch itself.
If this is working, then you need to look into the small sight glass in the top of the receiver/dryer, which is a small vertical cylinder. It should show a flow of clear fluid. Bubbles means it is low on freon.
But the controls could be screwed up, with the hot water staying on, the cold air not be allowed in, etc.'
Operating the controls should allow you to see these things working.
To go beyond this, like check the compressor, the expansion valve, etc., you would need to put a set of pressure gauges on, which are about $50, and come with instructions. There are 2 because you want to compare the input and output sides of the compressor.
