1997 Lincoln town car speedometer works sometimes other times is at -O- any suggestions as to cause??
Sounds like your vehicle speed sensor is bad or the pigtail that plugs into it is. This sensor is on the transmission and sends a signal to the computer to indicate the proper speed you are travelling on the speedometer. HTH. - Jim
I'll bet that the Speed Control doesn't work either. Either the Speed sensor or the gear driving the speed sensor is probably worn out. I don't think this model uses the ABS wheel speed sensors for the speedo. If it does, you'll need a scan tool to see what is actually being transmitted over the Network to indicate speed.
Add'l Problem: The instant mileage read out at times will read 00 then kick in with correct instant mileage as I drive.
ive changed all of that including the cluster and its still not working
