Not sure your premise re: no cycling-therefore no leak, is correct.
My a/c didn't work last year, compressor was not cycling, and all it took was a small recharge (no leaks detected).
I think you are right.
I jumpered the switch on the dryer and the compressor comes on. Looks like this is a pressure switch.
Got an inexpensive gauge and can of R134a fill kit and when I attached the can of gas to the car, with the jumper in place, the can got cold, and took some into the system.
The pressure gauge that came with the kit said it was in the cool area, but the air never got very cool.
This morning, the compressor once again will not cycle on.
So I suspect I have a leak, again. So it is off to the shop.
