interesting... the sample vehicle on alldatadiy is a 1998 Chevy Tahoe... from what I can see, the air box and the actuating motor look identical... however, the procedure for dash removal is far from "screw by screw", and the air doors are covered in very little detail...

Got the center console and the driver seat out.... I am committed now ))

Having trouble with this step

Remove all nuts holding the steering wheel and the cross bar below it, then pull the steering column off the bolts on a bracket closest to the firewall, and it will drop to the floor.

The "crossbar below it" is a metal tube that goes all the way accross the dash, there's no way I can make the steering column "drop to the floor"... WTF?

Well I did want to share pictures as I move along with this project (dash removal, hvac door repair), so, here they are.

Step 1. I removed the center console and the driver's seat. These are fairly easy so I did not bother photographing this step.

Step 2. The knee panel in front of the driver's seat. There are three screws along the bottom of this panel that are holding it in place, and two more metal snap things along its top, just gently pry those two out.

Step 3. Metal plate #1 under the steering column:




Metal plate #2:

Step 4. Steering column nuts. There are 4 of them, in two pairs.

Upper (further away from the firewall):




Lower (closer to the firewall):

Step 5. Dash pivot bolts.

These bolts, I think, prevent the dash from rotating. There are two of them, one on the driver side and one on the passenger side:




Step 6. Dash rattle stop screws.

There are three of those screws. They are right in the middle of the defroster vent. You can't possibly miss them. Take out all three. I will post a pic tomorrow.

At this point, I am stuck on the following two steps in the dash rotating procedure because I can't figure those steps out, help me please:

Remove ... cross bar below steering column, then pull it off the bolts on a bracket closest to the firewall, and it will drop to the floor. For the life of me, I cannot see how I can drop it to the floor without a plasma cutter...

Remove the two bolts attaching the dash to a plate above the glove box. Anyone got pics of this "plate above the glove box"?

The dash is clearly loose now but the steering column is not on the floor so I am not sure if I should begin "rotating" the dash...

Ok I got the steering column removed, the dash rotated, and found my broken door. It is all gross and melted... Off to the stealership looking for parts now. Will post the rest of the pics tonight, hopefully it will help someone else to do this job...

Kinda late for you now, but IIRC there is a piece of the tube that can be removed for the steering column to drop

Removing steering column

Step 7. Finish removing the steering column. To do that, I had to

remove the air bag fuse (this should probably have been done way earlier)

disconnect the yellow air bag wire (it is labeled in big letters, you won't miss it)




remove the bolt that holds the steering column wiring harness to its plug. when you unbolt the bolt, the harness should come out easily






remove the cross bolt at the base of the steering column. Its just one bolt. and for some reason I can't find the picture of it that I am pretty sure I took.

Finish removing steering column

My truck has auto transmission, so I also had to disconnect the transmission shifter linkage. There are two parts that need to be disconnected:

This cable needs to come out of its holder:



This ball linkage needs to be unsnapped (carefully with a flat blade screwdriver):








The steering column should come out now. Pull it out gently, it does not take any force at all, and it will come out:
