Speedometer + Cold Weather = No Worky

[Blink]

Like the title says my speedometer doesn't work when the temperature is cool/cold. I did a search on this and found some pretty old posts but no solution. Anyone know what the fix is to this problem?

Does anyone know how to fix this?

I'm having similar issues, mine stops working for a few weeks to months when I do a water crossing.

I'm betting on water getting into the big harness plug that is just above the starter.

But lately I have no time to verify this yet.

Clean all your electrical connections off your trans and then use dielectric grease in them and reconnect. Follow all the wires and repeat at all your electrical connections.
