AC system help 98 silverado

[inthechateau]

So I finally found my AC leak. The switch on the back of the AC compressor is the culprit. Is this the cycling switch or hi pressure ? Not sure what I need to be looking for. It is the 1136582 Delphi compressor. Any help would be appreciated.

There are three switches...

-low pressure cycling switch is on the accumulator at the firewall
-compressor pressure switch closes the recirc door on initial high pressure
-high pressure switch disables compressor if pressure is still too high

The cycling switch can be replaced without recovering refrigerant. I doubt that the other two offer that convenience. Do you have a picture of the leaking switch in question?

Sorry to piggy back but I didnt want to start a page... My AC only blows out the floor and the defroster... how can i tell if its the blend door actuator or a vacuum leak?
