i've got a 1990 v1500 suburban and i can't figure out how to get the column out of it to swap out the neutral saftey switch. actually i'm considering bypassing the NSS altogether. any thoughts or advice would be greatly appreciated.
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 in the past. Just put on your 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.
The other way of you want to give it a try is to follow the steering column all the way down to the firewall and then the switch is on top of it. You can be upside down when doing it, or you could do 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". It works 90% of the time to adjust the NSS.
Good luck and stay safe.
