Transmission failure in cold weather

My Girlfriend has a 2000 Dodge Durango 2 whl drive and anytime the temperature goes below 40 it will blow a fuse. Then it won’t shift and there is no transmission position display. It blows the fuse almost immediately after starting. Above 4o there seems to be no problem.

I wonder if the dew point is the more important issue than the temp. If condensation is forming and shorting the circuit that could blow the fuse. but that is kinda weird.

Apparently something is shrinking with the cold and causing a short to ground. You must have a wire with chafed insulation. Wiring problems of this type can be a bear to solve, but there are shops that specialize in automotive wiring. Tell them which fuse is blowing and they’ll track it down.
