Bad AC Accumulator Switch

Ok, I just did the paperclip in the accumulator switch harness to see if this was the reason my AC clutch wasn't engaging. The compressor clutch fired right up. Now my question is (I know jack $&%# about AC systems) if I replace the switch is anything under pressure in the can that I will lose or is it just a simple R and R?

When you jump the switch does it blow cold?

The write up said not to jump it very long and it's not hot here for the next couple of days. What I do know is that the clutch will not engage. Jumped it does. I see where you're going with this mike. Low on refrigerant. Dang I need a set of gauges!

From what I've read those gauges are junk. I'll see if I can swing up to my buddies work. It'll look funny parked in there with a bunch of Lexus'

Close enough for the one or two times it'll get used. the low pressure switch is probably fine. its not a common failure item. more likely that the system has a low charge. which means it has a leak somewhere.

The more I think about it, the more its starting to sound like a leak. The $20 switch is waaay to easy of a fix. Luckily the temp hasn't gotten crazy like it did a few weeks ago. Sounds like a trip to my buddies is in order

bearhugger is starting off with a positive reputation.
Mine was loosing freon also,found that the schawder valve up by the compressor was leaking,pushed it in and out a couple times and it sealed ok;put more freon in using the auto zone set up and no more problem.
