The gauge itself may be dead. I have seen one dead speedometer in a dash in 30 years, and that one was the old mechanical kind.
Check the cable from the transmission, probably broken.
Speed sensor. There is not a cable on this car.
It is called a Throttle Position Sensor (TPS), and is located on the throttle body butterfly cross shaft opposite the throttle cable cam.
You don't as it does not have a cable. You replace the speed sensor instead.
A 1996 Chrysler Town and Country does not have a speedometer or odometer cable. That signal comes from the transmission output speed sensor.
There is no such thing. The odometer is electrically driven from the PCM via the vehicle speed sensor. If the odometer has failed you need to replace the cluster.
There is no odometer cable. The odometer is controlled electronically via the vehicle speed sensor reading. The PCM converts this into an electrical signal and sends the signal to a drive motor located right behind your cluster face.
There is not an odometer cable. The odometer is driven by the speedometer. If the odometer is not working then you will have to replace the speedometer head.
There is no odometer/speedometer cable in that vehicle. The odometer/speedometer is electronic.
The odometer is electric, no cable.
Have your mechanic check the speedometer cable connections. They no longer use a cable. It is electronic. If the speedometer is not working but the odometer is, the problem is in the dash cluster. If both the speedometer and odometer are not working, the speed sensor in the transmission may be at fault.
I believe that 1995 was the last year for a conventional speedometer cable on a Ford Explorer , and then Ford went to an electronic speedometer with a vehicle speed sensor
