Since the instroment cluster has to come out then it will be best for higher learning. Purchase a Haynes Manual that is specific to you car. The cost is nothing compared to the wealth of information.
In a 2001 Chevrolet Impala, the fuse for the dashboard lights is located in the fuse box under the dashboard on the driver's side. Specifically, you'll want to check the fuse labeled "IP" (instrument panel) or "Dome" in the fuse box. If the dashboard lights are not working, it's a good idea to inspect this fuse for any signs of damage or blown connections.
check cigarette lighter for metal debris then change fuse.
