Can you replace the low pressure switch without venting the system? I need to replace the switch, but I don't know if all the freon is gonna come out. It would be lovely if the bung was fitted with a schrader valve to maintain system pressure when changing the switch.

I bought a jeep few months ago. And make the long story short, I just found out I need to get the low pressure sensor switch/sensor replace. So, do I have to vent out the system before I unscrew the sensor?
So here is my answer to the Jeep liberty A/C problem. According to my AC mechanic, it is a very common issue with the Chrysler AC compressors.
1. Turn on your AC to full blast in a warm day.
2. Open the hood, locate the AC compressor which should be on top and right in front of you.
3. Use a stick or a rock (just anything but your hand), and turn the compressor clutch clockwise.
4. If it engaged, cold air should flow into your car, which means your AC actually works, it just needs to re-shim.
5. Go to locate AC/Radiator specialist, pay them $50, it should take about 30 mins and you should be good to go.
