Default 1994 A/C Pressure Switch Leak

Has anyone had a leak from the A/C Pressure Switch? The switch I am talking about is in this thread:

http://forums.corvetteforum.com/c4-t...or-93-lt1.html

I was working under the hood today and the electrical connector that attaches to this switch is coated in a light green oil, it almost looks like coolant but it appears to be refrigerant oil. Has anyone replaced this switch with success? If I remove the switch will all the refrigerant be released or is there a shrader valve that allows you to attach and remove the switch? I noticed a green O-ring was loose and was on the body of the connector, it seems like it would seal something but I am not sure.

Any help is appreciated,

Patrick

Just wanted to give a quick reply. After scouring the FSM it appears the switch is on a shrader valve and can be replaced. Found a replacement switch part #36659 for $10. Will report back if the leak stops.
