Help with vintage air

Should be able to bypass the switch to make sure the compressor clutch is working. To replace the switch will require draining the system, it's under pressure.

I just bypassed the switch and the clutch does work

If there's power to the binary switch but none coming out when commanded and the system is charged correctly it sounds like a bad switch.

That's what I'm starting to think. For my sanity, how can I check to make sure system is charged correctly?

Throw some gauges on it to make sure it is charged. I don't see how they could charge it when the clutch was not engaging but I am not an expert. I know that when I charge them they have to be running....

Ok thanks. I wasn't sure about that either. I will try it tomorrow. Thanks

dhutton,
Our AC recharging machine will charge without the vehicle running. Charges into the high side and the machine can build some extra pressure to get in the required amount.

Should be simple enough for most shops to drain and swap a switch quickly.
