without seeing it im only guessing but, still looks like the pressure switch,, could it be that your system still has the same leak it had before, many will just simply re-charge without looking for a leak, the UV leak system only works if you have the light and goggles to check the fluid, you cant see small leaks with your eyes, also the pressure switch will still operate under high pressure conditions, such as blocked or choked condenser coil,
this is the coil at front of car next to radiator, also there is a drier in the pipework, to remove moisture in the gas itself, this can become wet and choke giving trips, check internal fan is ok and works on all speeds, also there is no blockage at the air in at the footwell,
does all the air vents work as they should, and is the air coming out the vent on cold setting actually cold, without a temperature probe there is not much more you can do, the big aluminium pipe going into the compressor should feel cold to touch while the small pipe coming out of it should be hot to touch,
try the above and let me know,
