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

posted by  someone claiming to be Robo Lobo on  Sat Nov 10 04:20 CST 2001 [RELATED]

Maybe I did not describe the symptoms well enough, Jake. The compressor begins cycling on and off *rapidly*, with 5-10 second intervals, pretty much immediately after I turn the a/c on. I simply can't believe that this is normal in a car that has a full charge of refrigerant.

The reason I was asking about the replacement of the low pressure switch is that it's a relatively cheap part ($36 through volvoparts.com) and it has been mentioned as a possible source of the problem.

But that being said, I absolutely agree with you about weighing the charge. My plan is to do that before my VIP warranty runs out in about 6 months, and see if the evap has gone bad again. And I'll do that even if I do replace the low pressure switch and even if my tick-tock sound has gone away.

Thanks for the advice, Jake. If you have any more ideas please let me know.
