Hey guys I need a bit of help I have the speedometer curse on my 05 tahoe. The needle had Ben jumping all over the place and finally stalled out wayyyy past the trucks speed limit I was at a standstill doing 200mph So Wat I did was switch out all of the stepper motors (might as well) pretty straight forward process with good contact on all points. Marked up the needles the whole 10 started it up I knew something was wrong wen I saw the mph twitch funky. All the other gauges were working like a charm. Xept the mph I drove it and it twitched its way up but wouldn't hop down now I'm right back at square 1.my question is I noticed my cruise control wasn't working and I know somehow the brake switch is related to that problem sometimes but the switch is fine. Can I rule out the vss? I'm a bit lost at this point.
