Trying to find this silly thing, its the vacuum control module that the 3 vacuum lines connect to, sits on the Heater/AC controls. This one has developed a leak and need a new one. Doesnt look like it comes apart. I've checked Year One, OPG, Ausleys and Jegs, no one seems to have it. Junkyard maybe?

Try an AC Delco Distributor that may have an older catalog with the listing.
