So. Pump replaced in the transmission and now the truck is running great again. Just passed emissions the other day, registered for another year.

Now, when it's cold out (which won't be for much longer here in Arizona), I get some weird symptoms in the dash. Gas level doesn't register, and the battery light is on. Turning the turn signal on causes either the wrong dash indicator to flash, or both, and the battery light will flash too.

Checking outside the truck, turn signals are working correctly, so it's just the dash.

Once the cab warms up, these problems go away.

I'm assuming I have a cracked solder joint somewhere. Question is, where should I start looking?
