HVAC Control Unit Reset?

[Tonyrodz]

I have the manual hvac headunit with the temp sliders. Does anyone know if there's a reset procedure? I bought a Dorman replacement--which initially worked, but now everything is coming out of the defrost. I don't think there is, but I could be wrong.

I know ive forgotten the auto hvac relearn trick, and don’t think there’s one for manual. However I know you can also pull an hvac fuse on the drivers side of the instrument panel to cause the auto hvac to relearn

@Tonyrodz has a Tech 2 so he could reset an auto hvac head, if he had one. I don't know if there is a provision in the Tech 2 for manual hvac reset.

EDIT: Tony, can't you command the HVAC head unit with the Tech 2, to see how the various blend doors, etc. respond?

How would you do this @ks03 ? While running--key on?

Yup, guess I need to start playing the lottery.

With the engine running, I’m pretty sure.
Did you try that method in the video?
