speedometer not working can you help
according to the owners manual this could be related to a problem with the ABS. I have the same problem and am looking for a diy solution. also from the owners manual the ABS controls the transmission , and my transmission is shifting roughly, which is what I noticed before I noticed that the speedometer wasn't working.
you can go to speedometer and out of speedometer
try your output speed sensor
You may need to replace the speedometer fuse. The speedometer cable can cause your speedometer to stop working. The speed sensor can also cause the speedometer to stop working.
Check the Tourqe Converter fuse, in the fuse box under the hood.(At least that that's where it is on a 96.)
