If the radio in your 1993 GMC Vandura isn't working despite a good fuse, the issue could be related to a faulty wiring connection, such as a broken or corroded wire. It's also possible that the radio itself is defective or that the ground connection is poor, preventing it from functioning properly. Checking these components can help identify the problem. Additionally, ensure that the ignition switch is providing power to the radio, as it may only operate when the vehicle is on.
