Just uncovered and started my 85 after a cold U.P. of Michigan winter...started right up, everything seem good except it doesn't read the miles per hour anymore...tach and other gages are good....speedometer reads some numbers when I turn the key but goes to O and stays there. Any thoughts on where to start?????

Check the wires on the speed sensor located on the transmission. (drivers side, lower back)

Maybe I'm missing something but you said you have only started the car. The speedo won't read anything other than zero until after it starts to move?

- it might be something as simple as plugging and unplugging the IP cluster's electrical connectors. the OP might not have a good electrical connection (signal or ground). unfortunately, it's a bit of work to get to the panel connectors. batee has a series of 21-youtube videos that covers just about everything on the clusters. whether you repair it yourself or not, a good source of information - covers just about anything you want to know.

before tearing into the cluster, first check....
