I suggest visiting autozone.com and register the truck there. It's free and will give you access to an online repair manual. The vacuum diagrams should be available there. Hope this helped and best wishes.

SOURCE: 1989 chevy silverado heater blowes cold air. both

Feel the hoses going into the heater on the firewall. If one is hot and the other is cool, then the heater control valve is not working for whatever reason. Check the flow valve.

SOURCE: I have a 1999 chevy silverado and I need to change heater core

Not a whole lot different. Just need to keep removing plastic down at the heater until you get to the heater core. Then disconnect it on the firewall side.

If dealer will not provide, there are books available which have nothing but vacuum diagrams. FYI, most newer cars have basic vacuum diagrams on a sticker somewhere under the hood. Dirt often prevents one from seeing it.

My chevy was running yesterday but, I don,t know


You can temporary run one heater hose into the other- either just take one side off the car and route the one hose right back into the water pump or - you can get a kit -
Either way - now you will need to replace the heater core inside the car.
