There is smoking coming out of my dashboard when I start driving. what wrong?

I agree. Fuses should break power connections, but melting wires will reroute power. And as the other expert says, it could be antifreeze steam, freon, or deadly exhaust gas (lucky that the invisible gas mixed with visible vapor).

Smoke is never a good thing. If the smoke smells like burning plastic, you probably have an electrical problem somewhere under there and should stop using the vehicle immediately and get it to an auto electric shop for repairs. Waiting could cause failure, or worse, fire. If the smell is exhaust-like, then you may have an exhaust leak under the hood and it is coming in thru the ventilation system. This should be checked out quickly, since carbon monoxide, present in engine exhaust, is a toxic poison that can kill if the concentration gets too high. If you must use the vehicle with exhaust gases entering the passenger compartment (and it is never recommended!), ensure all the windows are open to get plenty of fresh air, regardless of the weather conditions outside -- cold and wet is better than warm, dry, and DEAD!
