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
