HVAC Control Unit Reset?

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?

I'll try this tomorrow.

I was thrown out.

@Tonyrodz hook up your tech2

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

My theory on it was Everything off, pull fuse for 10 sec, while you’re waiting push buttons on the unit to drain any residual power, put the fuse in, turn the key on, without starting, wait at least 60 seconds without touching the hvac to let it do whatever it needs to do. I don’t know if it does anything on a manual control, but I think a auto will cycle all its actuators back and fourth to learn their positions

Both @swathdiver and I have tried the auto reset several times with no luck. Using a scan tool was the key to success for me.

So I replaced my mode actuator today and doing this didn’t make it relearn. However despite being installed in a different position than the one removed, it immediately operated properly.

I couldn't get it to work properly, so I returned it. Lady behind the counter was about to tell me she wasn't going to exchange it because I already exchanged it two other times. Dorman.....

my put it in, in whatever position and good to go... happened to be an ac delco

I’m thinking there’s lots of ac delco parts in salvage, won’t be any worse than dorman

There's a lesson there, about the manufacturer....

Just get a used one through someone like LKQ online. That’s what I did with my Silverado after I bricked the original while trying to update the firmware. I know mine was digital and yours isn’t but it shouldn’t matter- they sell and ship them. Www.LKQonline.com.
Edit: I just checked and they don’t list them for your truck but sometimes you can search eBay and they pop up. LKQ’s search function is fu*ked.
