Have you checked the fuses or relays? Sometimes that's easy to overlook. My next test would be making sure the a/c compressor has power and ground.

So if the A/C compressor is running and the low pressure line is getting cold but it is blowing hot air then it sounds like the blend door that switches from heater to A/C is stuck in the heat position, if this is a HVAC system a service center should be able to pull the codes to see if there are actually blends door codes, if it is a standard system then the vacuum system will have to be checked out for leaks or a possible vacuum servo motor failure.

Do you have a digital heat/A/C display or just knobs and levers?

Ok, pinch off the heater hoses ans start the engine put the A/C on and let the engine warm up, as this is happening the air output from the A/C vents should remain cool like the outside air, once the engine is at operational and making sure the A/C is on release the heater hoses, if the air instantly turns hot then the blend door is stuck. So if that is the case then the system will need to be repaired, if you have a shop manual for this car there should be a section in there on how to get the trouble codes for the HVAC system. I can tell you that most HVAC repairs get expensive very quickly, especially if the unit has to be pulled to get to a component.

Ok the AC used to work before one of the headlights caught on fire I want my hoses pops replace the hose and freon And no cold air :( @tennisshoes

Turn the A/C on then jumper th low pressure switch just for a moment and see if the compressor clicks on and the cooling fans turns on also. If it does both of those then either the low pressure switch is bad or the system is too low to close the switch, if either do not come on then it is time to drag out the circuit diagrams and start tracing down circuits that might have an open.

Ok so both fans have to working for the AC to kick on @tennisshoes

118,345

Yes, it may work briefly,but then the high pressure switch will sense the the pressure is too high cause there is no air flow and shut down.

So if the fan don't turn on the AC won't work @tennisshoes

118,345

It might run briefly, but once the high pressures get up the pressure switch will shut it down. If you want to try an experiment, get a large box fan and put it in front of the car blowing air into th engine compartment, and then turn on the A/C, then box fan should keep the high pressures low enough for the system to start blowing cold air inside the vehicle, I recommend that you do this with a cold engine, something like overnight cold.

If that works what do u recommend that the problem is @tennisshoes

Find out why the A/C cooling fan is not operating, it could be a bad fan motor, the fan relay, wiring problems, etc.

Ok so no fan no AC

If you follow the flow chart it would be no A/C signal no fan.
