92 XLT Speedometer

[fallguy51]

On a recent cold morning(Baltimore area, ~30degrees at 6am), the speedometer on my XLT suddenly lost its mind, and swung clear over past the 85mph mark even though I was only doing about 55. It stayed buried until I slowed to a stop, but it has continued to go past the end point as my speed approaches 50-60mph. I thought that it might be weather-related, ie cold air effecting the mechanism, but over the past week, local temps have been above freezing, with a couple of days in the upper 50's but the stupid speedo is still out of whack. Anyone else seen this problem and maybe have a cure that doesn't involve replacing the whole instrument cluster? Thanks!

Mine does the same thing on cool mornings. Also, it tends to flucuate about 10 MPH when it is cold, which throws the cruise control for a loop. Once it gets warm, it goes away but it takes about a half hour or so. Mine is a 5-speed 94 4X4. Any ideas out there?
