Test / Bypass AC switch

System is holding pressure but blowing warm air. I would like to bypass and or find a way to test it. Thanks

Pressure only tells us there is refrigerant ,,"we hope" in the system. There are 2 conditions that a hi pressure and low pressure switch will prevent the system from energizing the magnetic clutch for the compressor.
If those switches check out as OK, then we need to see why the compressor clutch may not be working.
