Good drawing of HVAC system components with part numbers needed. My old reliable vehicle (listed above) had the heater control valve disintegrate. I have purchased 3 manuals so far and none have any component breakdowns with drawings of system components. Can anyone share this with me?

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.
