Swapping auto hvac for manual

[Stroked]

I have an 04 suburban, has anyone swapped the digital automatic hvac control for just the dual zone manual control?

Pretty sure you’d have to flash the bcm so it knows.

This has been beaten to death for the last ten years. The simple answer NO. It can be done but you need to change the whole heater box, add sensors on dash, ducts and one ambient one outside. Need to add little fan on headliner that everyone thinks to be the onstar mic. With a lot of time and $$ anything is possible.

I think he wants to do the reverse, he wants to eliminate the complex system for the manual controls the LS models have. I don't think the manual ones have sensors in the duct work, so he could probably just leave the sensors in place.

Exactly, that’s why I think he would just need different controls and a bcm flash, and just leave the unneeded stuff as is. Either way, probably not worth it for a downgrade.

Oops! I missed that! So many people want to upgrade to digital. Try it and see. I don't know if the plugs in the back are the same.

Anybody ever follow up with this?

I would like to swap out my digital climate control system for the manual one.

Anyone?

Some things are just not worth it time and money wise. You'd have to disassemble much of the interior, replace, delete, add various components and program them to boot. Probably cheaper to supercharge it.

Probably... But if people can easily enough add digital in place of manual, it's gotta be easier to go the other way round. Wouldn't ya think?

some other person was adamant that it could be done if you changed the wiring harness, I guess there is only way to find out........ probably more hassle than what it's worth.
