Anyone have the part# for the vacuum switch
thats located behind the AC Control Panel.
It's the one with all the pretty colored vacuum lines :) .
I have been tracking down leaks and this seems to be the source.
 
I don't know the part # but if you have some time on your hands almost every vehicle GM made during that time period have those controls and the junkyards are full of them. That's how I fixed mine!:) If I find a part # for that I will send it your way.

Good luck!
 
I bought one last year from my friendly neighborhood GM dealer last year. I just told the parts guy what car I had and he ordered it. It was about $17.

There's a few on Ebay too..

From that one guy that takes anything that fits any Regal and calls it a "GRAND NATIONAL" part. :rolleyes:
 
Try these numbers.Vacuum selector valve with 9-ports(nipples) GM-16037778 Delco-15-71389. Vacuum Select valve with 2-ports ( there are two valves back there) GM-7897420 Delco-15-7975.

Thanks, those are the #s I need.
I've been chasing an intermittent vacuum leak for
some time now. It looks like the retainer that holds the
the two halves of the valve together gets brittle with age and
eventually brakes.
