Re: A/C low pressure switch- how to replace? 850 1996

posted by  someone claiming to be Jake on  Fri Nov 9 15:46 CST 2001 [RELATED]

My first question is why do you want to replace it as either switch rarely goes bad?

The low pressure switch is the one near the firewall and they simply unscrew, no freon will escape. I've seen a few of those fail.

The high temp switch is located on the compressor, very rarely a problem.

The high pressure switch is located just behind the right headlamp, doesn't fail as often as the low pressure switch (which isn't a common problem at all). Also just unscrews w/o freon loss btw.

The main cause of most 850 AC problems is a system low on freon and by now, most here know why too.
