Good Evening, this is a common problem in those instrument clusters from the cars to the suvs, the little stepper motors in there go bad. The dealer would replace the whole cluster. Some places repair them online, which is simply changing out the motors (worthwhile). Look around I would not recommend doing it yourself unless you are in an electronics field and know how to solder VERY well. Hope this helps.

My speed on my dash went out so as the rpm but my gas and other thing works, what could be the problem how do i fix ?


If both the speedometer and Tach quit working there is a high probability that the instrument cluster has checked out. The speedometer takes it's signal from the VSS (vehicle speed sensor) via the computer, and the tach comes from either the distributor or coils (tach pin) to the tachometer. Both these items would have to go out to cause your symptoms.

1. Check the speedometer cable maybe its not properly connected or you need to buy a new one.

2. If your having a problem with the gear check the transmission oil add some if the oil level is low or check the pressure plate and the release bearing and I hardly recommend to visit a good mechanic.

Speedometer/tach stopped working


There are 2 sensors on the engine that sent a signal to the computor and speedometer and tach. When one of these goes bad it can make the speedometer and tach go all over the place and also just stop working. This can also cause all types of engine running problems because the information being sent to the PCM will be incorrect all so. The units are easy to replace once you find them, it seems that they are located in different areas of the engine with each year the vehicle was put out.

97 town and country LXI mini van speedometer and tach not working


the cluster needs to be calibrated to the pcm before the speedo and tach will work. You will have to take it to the dealer to have it done. The last time I had to do it, it cost me 70 dollars.
