Re: Speedometer not working

Are the reverse lights working? If not, I bet that plug for the harness on top of the transmission has come unplugged or gotten damaged. Just fixed this issue myself a couple months back.

Be careful, when the speedometer doesn't work the car has no idea how fast it's travelling and can stall out very easily. Especially when coming up to a stop.
