Could be a variety of reasons for this. We have seen Vehicle speed sensors and or gear, speedometer head or even a unified meter control cause this kind of issue. Most common is a Vehicle speed sensor (VSS). Need to check for codes in computer. If it has a P0500 most of the time that turns out to be something with the VSS. If not would need to run some tests to track down problem.

Common problem with these instrument clusters. We repair these and many other instrument clusters at a very reasonable price. Visit http://www.mrwhizard.com for more information.

Are these related issues? What could be the issues? Possibly the instrument panel cluster needs to be replaced? Also, is it an easy fix that and the avg mechanically inclined person can correct?
I got a Nissan Frontier 4X2 XE with a 4cyl engine. Could this be a senser? or just a messed up gauge. The thermostat has been replaced.
