Default disassembly to get to HVAC control module

1999 LT 4DR 4WD
Its time to replace the HVAC climate control module again. I cannot remember where I got the disassembly information last time.
I have alldatadiy but it seems to be different than it was last time i used it.
does anyone that has the current version know where i can find the procedure for taking the dash trim and front of the dash off to get to the HVAC control module.
I have been searching and clicking, but I cannot find exactly where the step by step procedure is located.
If not from alldatadiy does anyone have another source.
Maybe you could paste it here for posterity.
thank you in advance for hour help with this.

I likely have that info I can post for you.

If I remember correctly, you need to remove the screws that hold the covers in place underneath the instrument panel and then you pry off the valance of instrument panel.

That would be awesome, thank you.
I just want to make sure I have the procedure / step order correct.
Appreciate your help.

Right. Sorry for the delay. I've attached the scans to this post. Be sure to report back on anything you find or if you have anymore questions.
