How silly of Alldata. The dash can't roll forward.
However, once you remove the steering column and other items, it can pivot REARward. It just swings back until it rests on the seat.
I've only done this once, on my '88 K1500. I had the service manual to guide me and it was still a pain in the ass.
In my case, I was replacing the rotted foam gaskets of the HVAC system, but I suppose you'd need to pivot the dash for access to the actuators.
Buy the service manual, follow the diagnostic procedure.
