Need help my truck is driving me nuts
i have a 2001 Silverado 2500 HD LS package extended cab 6.0 liter automatic with 4x4 with approximately 450,000 Miles . I’m having issues with my 4 wheel drive and my interior lights. Neither work. I only have lights on the 4 wheel drive panel when it first starts than nothing. Information center flashes “Service 4 Wheel Drive” I’ve replaced the switch panel and the front actuator and checked the grounds on the frame. No luck. As far as interior lights I have nothing dome, light map lights, door courtesy lights nothing works. Information center keeps flashing “Cargo Lamp On” (not working either). Just replaced driver door latch hoping it would fix the problem, but again no luck. I’ve had the truck for about 1 1/2 years and don’t want to keep replacing parts with no results. Any help or advice would be greatly appreciated. Thanks.
