Speedometer gives a wrong reading for Yukon XL 2003?
Need to know what is wrong with it. If both the speedometer and the odometer don't work, I would suspect the VSS (Vehicle Speed Sensor) located in the back end of the transmission is bad. If only the speedometer doesn't work, I would suspect the instument cluster has to be replace with a reconditioned one from your local Chevrolet dealer. Contact a dealer for a price.
Broken tooth in speedometer head. Replace speedometer head
My speedometer works and the odometer does not because there is a plastic gear in the odometer that is broken.
Yes, tires that are larger or smaller in diameter than original factory size will cause a car's speedometer to be wrong.
whats wrong with it?
that depends what is wrong with it
If speedometer itself is working then gears inside the assembly are damaged.
Why doesnt your speedometer work on a 02 Mits Galant
Depends on what's wrong with the speedometer. Try re-soldering the contacts on the mainboard behind the instrument panel.
