Question about GMC C2500

1 Answer

My speedometer isn't working on my 93 GMC Sierra 350 5-spd Muncie 2wd. The tach and all others work, just not the speedo. I replaced the cluster and still no speedometer. Where is the speed sensor located? I need to see if it's even plugged in.

You will find the VSS (vehicle speed sensor) on the left side of the tail shaft of the trany.
Please let me know how it goes.

    It either has to be a connection on one side or the other.

    Iwould check output voltages, look for battery positive, and frame grounds.

Tachamererter intermit dont work

Tachometer failures are very common on this brand. The tach will tend to hop around first and then just stop.
The most common failure for this concern is a faulty tach in the instrument cluster. This can be checked by using a scan tool to observe the instrument cluster data for the r.p.m. signal, if the scan tool shows a tach signal (RPM) signal then the instrument cluster isn't displaying this signal and is faulty and needs replaced or repaired.

Hope helps.

Chevy cavalier 2005 speedometer stuck not working

That Cluster will work But, You will have to get an Installation kit if you want the Tach to work. Everything else will hook up the Same. You have a Distribution Box (Fuse Box) Under the Hood on the Drivers Side, There is a Fuse in it for the Speedo. Inside the Cover to the Box is the Fuse Diagram or in the Back of the Owners Manual.
