im looking for a complete vacuum diagram for a 85 k10 4wd my heat and air switch dont work it only blows on the floor and i was told its a vacuum line that is gone and i would like to get it working again thanks.....

Is the vacuum hose hooked up to the reserve cannister and is the cannister hooked up to manifold vacuum.

if your talking about the one under the head lights no its never been hooked up since i owned the truck now ive only had the truck for about 3 months now and not sure everything about it thanks..

Thats the charcoal canister.  Vile's referring to the black plastic ball on the firewall, passenger side (at least on my 83).  Should have a tiny vacuum line going through the firewall into the cab and one going to the intake (or I guess the carburetor vacuum would work).

Driver's side on my '84

There's one on the driver's side too, but its for cruise.  Again that's on mine, later models might be different.

yeah i do have that but i thought it was for the cruise that i no longer have so it might be the right one im looking for thanks
