Message: [QUOTE="BigRed97, post: 711174, member: 1979"] hey guys, im a little stuck on this. my speedo doesnt work. it started a few years ago: sometimes in the morning the speedo wouldnt work, id give the top of the dash a little smack and it would come to life and be fine for a couple days or even a week or so. it was like this until about a month ago so i just lived with it. now, since I had the dash out again to dye it black and change the cluster lighting, it wont work at all along with my odometer (every other part of the cluster works fine) so far i have: -pulled out VSS and cleaned it with no change(it had a few metal shavings but nothing dramatic) -replaced the speedo motor inside the cluster with a known good one from a spare gas truck cluster, with no change -replaced the small circuit board inside the cluster that has cables running to speedo and odo with no change -swaped cluster from my buddys truck, speedo did not work in my truck -hooked up the old snap-on brick, read VSS signal while driving and scan tool shows correct speed, although it did have a VSS code stored. can any one tell me what voltage range i should have at the VSS+ wire at the cluster plug while stopped and while driving ? thoughts? GEM? [/QUOTE]
