Today I spent about 8 hours removing the dashboard and half of the cowl trim and engine compartment out of an H2 just to change a fresh air door actuator.

Its just a cigarette box sized stepper motor that operates the air doors in the a/c unit.

Unfortunately due to slack engineering principles they use at GM they put some of them between the firewall and a/c unit which is BURIED deep in the center right of the dash.

And that was with cutting corners, such as only pulling the dash and a/c unit back just a foot or so to access the actuator and door.

The crazy factory manual would have us spending two days removing the entire dash board and a/c unit from the vehicle.

Oh, the stories I could tell about H1s and H2s.
