Thanks diesel4me. I'll get in there and see what is up. I'll take pics too, if I don't freeze first.

Ok, so here is the pic of this thing ...
Now how in the world am I supposed to get into that thing, remove it, adjust it, take it out for a nice dinner ... I'm not seeing how it comes off.
Is it a snap fit? Can I just jam a screwdriver in there and pop it off or something?

2 bolts from the (impossible to reach) top of column. I believe gm installs these previous to installing the column, so its hard to get to and your blind trying to find the bolts. I believe there 2- 5/16's head bolts one on each side of the switch.

Thanks. I'll get in there tomorrow and try to remove it ... and adjust it when it's off I guess.
All they had to do was put that on the bottom and it would be so easy but noooooo ....

There are two nuts that hold the steering column to the dash board directly under the column, just inside the dashboard. Take those off, drop the column, don't be shy about yanking on the steering wheel to get it to come off the dash. Most of the time they will fall off. but I've had a few get really jammed in there. Just put on your big girl panties and give it a yank.
Then you can just use a 1/4 inch ratchet and a 5/16 socket, loosen the hold down screws, make your adjustment, then shove it (the column)back up in there and tighten up the nuts.

Update - problem solved!
Long story short, you don't need any tools for the 91. Just grab the entire switch housing from the top and slide it left or right. It ratchets each millimeter or so. Move it until your lights come on correctly. That's it!

And this switch is all the way on the top closest to the firewall? so you can only reach it by being upside down on the floor?

Yeah, see my photo above. Just follow the steering column all the way down to the firewall and then the switch is on top of it. I happened to be upside down when I did it, but now I realize I could have done it by kneeling outside the truck and reaching in under the dash.
Give it a good push, it's pretty firm, and be careful of sharp edges that might bite you. I just sort of grabbed the whole top of the switch and pushed it towards the center of the cab, probably about 1/2". I just checked and it is still a little off so I will have to try again, but it works 90% of the time now where it did not work at all before.

nice i think it'll be a high of 22 tomorrow, so I'll give it a go then Just have to chock the tires and toss the truck in reverse and run back and forth from the switch to the reverse lights to see if they come on eventually.

Tip: Don't start your truck, just put the parking brake on and throw it into reverse without the engine running!nice i think it'll be a high of 22 tomorrow, so I'll give it a go then

Just making sure. I was an idiot and did it with the engine going first, and while I was standing outside my truck tha parking brake magically popped off and my truck started driving down the driveway.

wow haha that must be quite the experience. Since my truck is lifted so much I just stood next to it and reached up to the column around a bunch of wires and found a plug and barely touched it and heard click click click. Took 3 adjustments to get it to work, but just ran behind the truck and back under the column with the wheels chocked and the truck in reverse with the key in the on position and engine off. EASIEST fix I've done on the truck bar none. Took 5 minutes tops and I didn't get dirty lol.

Glad to hear. I just found out that my switch is defective. No matter what I do, the lights don't work any more. Guess I am going to have to pull it out anyway! Grrrrr.
