Great Forum,
I have replaced my comp, orifice tube & accumulator system works great only when I jump out my low pressure switch on the accummulator, hi/lo pressures are with in ranges..
I do remember that there was a schrader valve on the low side port were the low pressure switch is located. should I have remove this prior to installing the low pressure switch?

No, change the switch and don't touch the shrader valve. If you needed to change it, that would be done with the system empty.. The shrader valve will hold the refrigerant in while you change the switch..
Have to ask, did you pull a deep vacuum and charge the correct amount of R134a back into the vacuum>??

So, the schrader stays in right? yes I pulled it in a vac to 29" and wieghed in the charge to 4 lbs 8 oz chart say's 5 lbs. I'll probalbly trim the charge once I replace the switch.
Is this part available on line or OEM from the dealer?

May thanks

The cycling switch on the accumulator is Acdelco part number 15-2832 which can be cross refenereced by most auto parts stores. If you want to buy it from the internet, you can e-mail the guys at AcKits.com and they can get it for you pretty fast.... Hope this helps..

Almost forgot... Be sure to change and lubricate the O ring where the switch goes.. Don't over tighten, it's plastic and can crack easily....Hope this helps..

Chick or Tim,
when I go to repace the switch does the oring go inside the pressure switch or on the outside of the male fitting that houses the schrader valve on the back shoulder?

Many thanks

It will go right where the old one is, ....sometimes they do come off with the switch, in which case, you'll see the groove on the fitting that holds it in place, just under the threads on the fitting..Hope this helps..

Since this topic does come up now and again, here's a pic of where the O ring on the "cycling switch" goes. It's a captured O ring with a groove under the threads, and thats where it sits. Be sure to lube it so as not to rip or tear it. Don't overtight as you can crack the plastic switch..Hope this helps..
