I think everybody that has read up on hooking up there WB to there A/C pressure switch knows that "maybe" they should NOT use there A/C while the switch is unplugged.
I can tell you 1000% do NOT use the A/C and I found this out by not using the A/C, but the Heat!!! The car will still use the compressor even if you have the temperature set to 90* and you think you are using the heater, until you press the little button that looks like a snow flake with the line thru it to turn of A/C mode.
I of course know this because I let out about 1/3 of my A/C refrigerant/oil the other night while running the heat, was sitting in a drive thru line and all of a sudden I here a really loud hising noise and yep it was the A/C line.
Just thought I would share that so no one else does this to themselves.
