I've had a problem for a while with my speedometer where it would do strange things. Initially the problem started where the speedometer needle would sometimes hang up and then jump to the current speed. Eventually it got to where sometimes it would be totally dead (0mph at any speed), or it would spin all the way around the dial and peg out against the bottom of the 0mph peg, or it would wander around between the 3 and 8 o'clock positions on the dial. Tapping the panel would sometimes make it start working normally or make it enter one of the other wierd mods of operation and it was also affected by changes in ambient temps. The odometer never had any problems. Anyway, I disassembled the speedometer cluster and found several broken solder joints where the 4 pins that go to the speedometer's meter movement connect to the board with the IC that converts the incoming pulse stream to a voltage for the speedometer. Cleaned up the contacts and resoldered the contact pads and its been working fine ever since.
