Can you tell some more details about please? I have a 1988 gmc sierra 1500 and I replaced the lower switch too but still not working I did the by pass like you did and my compressor start working but like I said when still not working with the new switch I have to replaced also the high pressure switch (purple one) because was damaged but the new one came with 2 wires, the extra one was for ground. I know my Ac compressor it’s working but I can’t find the problem
The part needs an 'o' ring installed inside the switch so it won't leak freon. Don't forget .
Is the an o ring to seal?
