Yes. That winter air will get ya. Swap for that Spring/Summer mix.

If it's not a ground issue (probably is) then find a speedometer shop. Way cheaper than a dealer. In my parts I use Zepco Speedometer Repair. All things electronic/instrument cluster/etc...

sell it while you can same thing would happen to my wifes suburban. Mechanic said wiring harness needed to be replaced but who knows. Its hard to trace down the source of an electrical problem especially when its random

Seems legit. Any help with coming down to the wire on figuring out what this is?

I think there's a loose nut between the seat and the steering wheel!

In the short run, pour coke or dr pepper on that terminal and it will eat the corosion off for now.

Corrosion is a symptom of a bad connection somewhere, usually on the ground side.

New terminals, and Battery. If the cables are showing signs of corrosion past the terminals likely need to replace the cables. They are quick and easy to swap and relatively cheap, direct replacements available. I have noticed the Batteries with the "eye" that is suppose to show the "State of Health" tend to leak around the terminal bases. I have no clue why. Just my uneducated observation these past 20 years...
