People should know that there are two versions of the switch; US95 is for the standard steering column and US105 is for the tilt column. US105 has the bracket reversed.

That other rod, that is on the left side of the steering column, is the switch for the turn indicator - I think. When I removed the ignition switch, it freed the turn indicator switch and that rod fell completely free - It would be best to tape that rod to the column. The ignition switch rod was hard to get out of the switch.

The other rod on the left that is easy to see is for your high beam switch at bottom of column...when you pull back on the turn signal lever, there is a little plastic piece that pushes a metal rod leading down to that white switch with the little hole for the rod to set in...that rod pushes the switch from low to high beam and back to low and so on:)...my problem is the electric ignition switch or its out of adjustment or worse the rod is bent and that will cause me to dissect my entire steering column.

Heads up guys...big diff between the switch on tilt and no tilt.

My truck isn't cranking or starting when it's hot. If you drive it for a while (like 20min or more) and then turn it off it won't start again for a while. All of the gauges go up and down when you turn the key but it doesn't crank, click, or anything when you turn the key. You have to wait at least 10 to 15 minutes. Then it starts fine. Can't figure out why. I bypassed the clutch safety switch but that didn't change anything. Someone told me to install a relay in the ignition wire but i don't understand why that would help.

You said "drop the steering column". How far should it go? My steering wheel dropped about 1 inch, possibly less. The brackets out of the way help, but still I can barely see the switch. I did get both switches disconnected. It is helpful to know that both connectors have two latch releases each.

The column doesn’t drop a whole lot it’s still a bit of a pain to get in there.

You can drop the whole thing if you remove all four screws at the base of the steering column

I've got an 88 Chevy C1500 that's not wanting to turn over or start at all. At first, I thought it was the battery, so i replaced that, which didn't fix it. Then i figured maybe it's the starter, so we replaced that & it still didn't work. Next, we thought it could be the ignition control module, so that's new now, too. Still nothing. The last thing i could even think would be the issue is the ignition control switch itself, like in this video. Would you have any idea whether or not replacing this switch might solve the dead truck problem for me? I'm not super familiar with vehicle work quite yet, but I've already sunk $300 into parts with no result so I'm a bit hesitant to do much more experimenting with it atm haha.

sorry for the late reply but it could be possible that the ignition switch is bad. or maybe a neutral safety switch if its not turning over at all. its hard to say honesty electrical stuff can do weird things even from just a bad ground. Best of luck.

I am in similar situation with a 94 g20. I am going to try a new ignition switch.

What’s the size of the screw that holds the ignition switch to the steering column ?

@steverose2405 Ай бұрын

What symptoms indicated that the switch needed to be replaced?

@willyworks52 Ай бұрын

After the truck started and I let off the key the start was still spinning inside the starter body. After replacing the switch I no longer had that issue.

@rocky7369 6 ай бұрын

What problems was it giving you? My 88 drags on starting on occasion battery, alternator and starter are good trying to find another cause to the problem.

@willyworks52 6 ай бұрын

The problem I had with the old switch was it would always giving power to the starter even when it wasn’t on the run position. One day I went out to start my truck. I turned the key over and the starter engaged the flexolatw and turned over the engine and it started with no problem. when I backed off the key to leave it on the run position like you normally would the starter disengaged like normal, but kept spinning inside the starter body itself. I should the truck off and I disconnected the battery and when I went to hook it back up, it did the same thing the starter was spinning a side of its body. It did it two times and fixed itself but I went ahead and replace the switch.

Does anyone know if you change the steering column from a manual truck and put another steering column from a automatic one would affect. My truck won’t start

Yeah, you don't do that

How do you get the adjustment right on this? I replaced mine a couple of years ago and can't remember how I did it, but today my key stopped turning all the way forward (yet somehow catches just enough for crank to work for now) and my wipers sometimes don't work unless I jiggle the key. I suspect the linkage from the lock cylinder to the ignition switch isn't aligned just right or something. It looks like the mounting holes for the switch are elongated, so I would assume it is adjustable, but I'm not sure what needs to be in what position to do it correctly.

@willyworks52 6 ай бұрын

I know the neutral safety switch on the bottom of the steering column is adjustable. As for the ignition switch im not sure. I would have to dig into myself and look aground.

@majoraslayer64 6 ай бұрын

@@willyworks52 I actually took it down, made sure it was adjusted in the same position yours is in, and put it back up. I replaced my lock cylinder because I think that was my main issue, but adjusting the same as yours seems to have done the trick. Thanks for posting the video!

@steverose2405 11 күн бұрын

I had problem with the adjustment. If the switch (in the mounting slots) is too far down the column, the switch will not engage the starter. If the switch is too high on the column, it will crank, start, and run fine - but it will not turn off. I had to apply my manual choke to kill the engine. It wants to be somewhere in between, probably varying from vehicle to vehicle.
