Good diagram of HVAC system needed

Hello, I'm Danny.

We have access to pictures but it's more of individual components. I've attached a few pictures below of some system components on your Suburban. I've also attached replacement steps for the heater control valve you mentioned that failed. I've also attached a picture of the heater control valve Chevrolet part number. Let us know if you have any further questions on this issue. Hope this helps and thanks for using 2CarPros.

Thanks for the reply Danny.

The heater control valve I am replacing is located in the engine compartment next to firewall. Drawings I am looking for have indexes showing what part #_ is with part number. I have looked everywhere and have paid for 3 manuals and none of them have such drawings, detailed.

Hello again.

Is the valve you mention be in the number 6 photo I attached in my prior post in location # 4 of said picture? Let us know and we'll go from there. Hope this helps and thanks again for using 2CarPros.
