How do change the dash lights in a gmc savana 2500?

To change the dash lights in a GMC Savana 2500, first disconnect the vehicle's battery for safety. Remove the dashboard panel by unscrewing any screws and gently prying it away to access the instrument cluster. Once the cluster is exposed, locate the burnt-out bulbs, twist them counterclockwise to remove, and replace them with new bulbs. Reassemble the dashboard and reconnect the battery to test the new lights.
