    I have put up a couple posts trying to get help with my speedometer not working, but I have received much help. I changed the vehicle speed sensor thinking that would solve the problem, but that did not work so I decided to get a multimeter and check out how much voltage is going to the wire that goes to the speedometer/ back of the instrument cluster. I found that this wire ( light blue/black ) is only receiving about 1/4 of the voltage that the other gauges are getting. Is this normal? Might this be my problem?
