AC Compressor Switches (Page 6/7)
88TTops AUG 21, 06:24 PM
Hey guys, I have been stalking both rwd’s posts about A/c.
I recently am trying to fix mine, but I ran into a massive problem. I have tried both style switches/part numbers and they are all too big to fit in the new compressor. The compressor was ordered in a kit I got to fix it all, it’s an H6, that’s all it states. Any help is much appreciated! I can’t cross match a proper fix.

WOW!

I just realized that I originally added my $0.02 to this old thread back in 2011 (pg. 1)

That was a full year after I had overhauled the entire A/C system on my 87 GT in 2010 https://www.fiero.nl/forum/Forum2/HTML/107037.html

My son has since taken ownership of that car and 13 YEARS LATER the A/C system is still working better than ever (here in the Florida heat)

Just goes to prove the old adage that "even a blind squirrel occasionally gathers a nut", and apparently I managed somehow to do it all correctly.

I've only ever seen one size of switch, have any pics? Might be a snap ring in the port, or on a lot of compressors, the cavities are not machined to accept switches, for applications that didn't have them.

Hello I have been looking at all the A/C write ups and i am having ZERO luck getting the right switches. If I get one that's supposed to be on a GM its too small for my new compressor. I bought the kit from partsgeek.com I believe. It said it was for a Fiero and its about the same size compressor and accumulator was a flawless fit so i don't think I got the wrong one. Dose any one have a updated list? The compressor in my kit is a H6. Thanks any and all help is appreciated, car is just sitting on jack stands for the last week and I am getting frustrated!

Here is some pictures, I know the snap ring is in there but when i take it out the switch diameter is only 14mm where the old was 22. I have used both your write ups for all my parts all have worked until i got here.
Also sorry for double post and late responses I dont get notifications when there is a reply. Thanks for any help to get me in the right direction.

Here are the pics:





On the new compressor: Did you remove the snap ring, AND the metal plug? The plugs are there for applications that have 1 or 0 switches.

If you look closely you can see the o-ring groove. I have taken the snap rings off as i have tried to install the new switches based on both of your build threads. ALL of them are way to big. This seems so weird to me that everything has literally, bolted perfectly into place besides these pressure switches.

That metal machined surface behind the snap ring is a plug, it isn't part of the compressor body, you use a pair of pliers to remove it. Then the switch will slide right in.
