have a 99 mv6 3.0l and have lost my speedo, and pas has got really light, there are no warning lights that have come on. when i used a scanner no fault code found, any one got any ideas or could it be the dreaded abs/tc ecu (aaahhhh). i had this repaired about 6 months ago when my abs and tc failed also had an intermitent speedo fault as well, but has run fine since.
Afraid, that's the classic symptoms of the beginnings of ABS ECU failure, the level of PAS is determined via the speed feed from the ABS ECU as is the speedo.
You could try cleaning up the sensor on the NSR wheel as this is where the feed comes from, but 99% it will be the ECU.
Sorry bud.
