Cluster odometer works intermittently even after new gears, everything works..

[Gregs///M]

I have this issue but it seems to happen when it is cold out. I replaced the gears and the main circuit so I have narrowed it down to the speedometer/odometer unit itself.

I will have to check to make sure i didn't tighten the screws too tight on the gear cover but I was thinking since it happens in the cold, maybe there is a solder joint that is coming loose in cold weather. Usually it has happened when it is below 40 F. Maybe I should replace the speedometer, but if I do, that will negate the odometer gears that I replaced so I'd rather not do that.

If your speedometer is VDO brand, assume solder joint or solder trace cracks, super common!
