VSS again. 1997 Chevy K 1500

[Tony G]

Ok, I'm lost. Been reading the posts and I think I overloaded on what everyone has done and how this problem is fixed. Intermittent issues of the speedo, tach, odometer not working, coinciding with the transmission starting in 3rd gear. It starts in third from a stop and won't shift into overdrive. I'm not posting this in the transmission section because it is not a transmission issue. At times, the truck decides to cooperate and everything works great, even the speedometer is dead on accurate, according to the radar road signs. Life is good when the truck gets all the proper electrical signals from the proper places. I'm not going to be able to diagnose this. I just don't have the skills. But I can follow advise pretty well! Where does one go after one has replaced the VSS on the transfer case and that hasn't fixed the issue?

Ignition switch, my 97 did this exact same thing. Got a new ignition switch and cured it, everything works now.

Just the ignition lock cylinder. like this one? WHY does it say it needs coding at the dealership. The immobilizer thing didn't come out till 1998

Nope, ignition switch: https://www.amazon.com/Standard-Mot...-----------1&vehicleName=1997+Chevrolet+K1500

It's costly, but that's the only thing that's going to fix this issue.

I was afraid you were going to say that. Ouch. 105 dollar sensor yesterday and 120 today. But thanks a lot

Is anyone else going to chime in here?

Ran into a little problem replacing the ignition switch harness. There are three wires going into what appears to be a plastic collar around the steering column, close to the firewall, inside the cab. I can't see a way to see what is under there unless I destroy that black plastic bit, which I'm willing to do, if I know what is under there. Is there a connector for these wires under there? The wires are blue, orange and black. Thanks.

The black plastic box where the wiring harness connects to can be pulled out to get to that 3 wire connector on the side of the column. It is fairly easy to get to once the box is pulled down, but there is some soft insulation around the connector, kind of an inconvenience. This video helped me the most on doing it:

Great video but it doesn't cover those 3 wires to the steering column. I just can't get those bloody things to come off. That harness in the video does not have those 3 wires.
