I've been working on my A/C for a bit of time now. No leaks, compressor works as it should, just sometimes it stops on me. Each time I disconnect the battery for a while the A/C comes back on, sometimes for days, sometimes for a few minutes. I've replaced the switch nearest the dryer with three prongs and wires. I also bought the low pressure switch with the two prongs and wires.

My problem is the first switch near the accumulater (dryer) was easy to find, where is the low pressure switch on these vehicles? I've looked through my Haynes manual and can't find a mention of it and other places say "Low pressure line near high pressure cycle switch" and that doesn't explain much since I can't see it. Since I already have the switch I'd like to not pay a million dollars for someone to spend five minutes putting it on. Do any of you know where that is located on the line so that I can swap them? Thank you for the help guys.

I believe the switch is both a high and low pressure sensor.
