It is probably the speed sensor. It is located on the transmission and sends an electrical signal to the speedometer.
my heater fan in front of my 2004 chevy venture van wont work
Why doesnt your speedometer work on a 02 Mits Galant
its broke
this is usally caused by your speed censor is gone it should be located on top of transmission drivers side of car it is the one with 2 wires plugged into it.
The speedometer doesn't work. It doesn't respond to the speed we are going.
ground wire from tank to frame needs to be cleaned and remounted
If the brake lights do not work on Chevy Venture van 2000, try to disconnect the brake switch. Then short the two contacts of the connector to check if the brake lights are now working.
broken cable? Broken gear at transmission end? Broken gear at speedometer head?
they require a special tool to disconnect them.
getting speedometer to work on a 91 chev it is most likely the vehicle speed sensor on transaxle pass. side, about 40 dollars at part store
If both the speedometer and the odometer do not work I would suspect the VSS (Vehicle Speed Sensor) located on the tail shaft of the transmission is at fault. If only the speedometer doesn't work it's probably a problem with the dash cluster.
