OK guys my speedometer in my 93 p/u is acting crazy. Sometimes it sticks and jumps up or down and sometimes jumps down when I use the turn signal. I pulled it and cleaned all the contacts but it's no better. It's not cable driven so it must be in the cluster right?????

 

no it could be down on the tranny where the speedo sensor is too. check that connection to see if it is messed up too, also if u tap on the dash when its acting crazy does it do anything?
