My 1992 Voyager with 3.0 has the original engine and automatic transaxle, and has 150,000 miles on it. Everything works fine except for a problem with the instrument cluster. For a couple of years now, the speedometer regularly sticks after the vehicle has been on the road for a time. This time seems shorter in summer than in winter, so I suspect that something is overheating but I'm not getting any codes and one reputable shop has been unable to find the problem. The speedometer will stick on virtually any number. As examples, if I've been driving at 70mph and decelerate, it will stick on 70 all the way down to a much lower speed; if I've been driving at 30mph and accelerate, it will stick on 30 until a much higher speed. I can bang on the steering wheel or the top of the dash board and get it to read normally. Sometimes, if the vehicle is stopped, I can move the gear selector to park and then back to drive and this will get the speedo unstuck, but I'm thinking that this is due to the vibration caused by this process and not the actual gear change, but that's just a guess. Quite often when the speedo gets unstuck when the vehicle is stopped, the speedo will read 10mph. I have also noticed the fuel gauge sometimes sticks, too, and can be "reset" in the same manner as the speedo, but since this gauge normally moves very slowly, it's not really a good indicator of the problem. I can't figure out if this is a bad speedo, a bad instrument cluster, a connection somewhere that opens as the temperature of something like a light bulb warms it up over time, a sensor that goes bad after it has gotten hot, an ECM problem, or a combination of things. Can anyone suggest what I do to isolate the cause for this problem? Thanks!
