Brake lights work but tail lights won't work with front lights which are needed at night on 2000 Chevy Malibu! When inspected, everything was fine until inspector changed my left tail light. Now tail lights don't work and lights on dash are out!

The Tail lights and Instrument lights are usually on the same circuit so both will go out if the fuse for the circuit blows. Check for a blown fuse for this circuit and replace if out. If fuse continues to fail, check the tail light or side globes for a faulty globe and replace if necessary. Also check for any chafed wires that could be shorting to the body causing the fuse to blow.
