Question about 2001 Chevrolet Silverado 2500
Need diagram for 1991 Chevy Silverado heater hose routing.

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.

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.

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.
