If the factory amplifier in your 2002 Lexus GS430 is not working, first check the fuse related to the audio system, as a blown fuse can cause the amplifier to malfunction. Additionally, inspect the wiring connections for any loose or damaged wires. If these steps do not resolve the issue, the amplifier itself may need to be tested or replaced, as it could be faulty. Consulting a professional audio technician may also be beneficial for a thorough diagnosis.
