A/c compreesor switch or non-switch type?
« on: February 15, 2008, 12:37:06 pm »

What's it look like and what's the sticker on it say? What do you mean switch or non switch?

Just to add the R4 is radial, it's short and fat. The A6 is axial and is long and skinny.

Yeah, it's short and fat.  I'm trying to locate a replacement, but everyone asks me if it's a switch type or non-switch type.  I really don't know what that even means -

They must be talking about the high pressure switch. Do you have the old compressor? If you look on the back of the compressor there will be a connector sticking out of the back.

I'll check it tonight -  So, if I have a connector on the back it's a switch type?

What's the part # on your existing compressor?

Look at page 220

Couldn't locate the old compressor, but it looks like it must be a switch type.  The v-belt compresssors only came with a high-pressure switch if I'm reading the chart correctly.

that sounds like a blow off valve. What's the part # on the tag?

What's wrong with yours by the way? I checked with my vendor and they said they end up superceding each other anyway so just go with switch type. Here's a used ebay one http://cgi.ebay.com/ebaymotors/80-81-82-83-84-85-86-87-GM-CHEVY-A-C-COMPRESSOR-1131198_W0QQitemZ220190822171QQcmdZViewItem

Not sure what's wrong with mine.  It puked oil all over everything and stopped working back in August (when it was 95+ degrees in NC) -

I'm looking for a new one, and the non-switch type is much less expensive ($50 or so)  Looks like mine does not have a switch on it, or I can't find one -  The only thing I see is the valve on the back with the spring -
