2009 prostar A/C compressor stays running. Help

[earnies2]

2009 prostar A/C compressor stays running even when I got the temperature knob on hot and the function knob on dash or floor.
I haven't used the truck for 9 months (motorcycle accident than covid) the freon leaked low due to a leaking Schrader valve, so I decided to also change the thermosters whal it was evacuated. After that I gassed it up its nice and cold but the compressor won't shut off, if I unplug the high side switch it shuts off the compressor when I plug it back in the compressor comes back on in about 15-30 seconds. Pressurs are good, fan kicks in at 325psi, compressor was changed last year . I'm stuck! Does the BCM turn the compressor off or does the rotary switch turn it off? Any help is appreciated. I have been down for 9 month's and barley holding on.
Thanks in advance
