Hi, new to the forum but am hoping someone can offer advice on this old thread.
I have a 02 avalanche with 130,000 miles, something like this just happened to mine. truck starts great but as soon as I touch the tilt steering to move into driving position the dash gauges go out and it drives like it is in another gear. If I leave the tilt up things work fine.
If you feel it is the ignition switch does that mean the key cylinder only or does that mean the wiring harness assembly or should I be changing both?
Thanks for your help.
