2024 Gmc Sierra 2500hd Service 4×4 Light On. In this video i outline possible causes including diagnosis and repair of common issues effecting chevy, gmc and cadillac trucks and suv’s such as chevy silverado, tahoe, gmc. I bought the truck about 3 months ago and, when i bought it, it shifted a little funny, but it.
When i first entered the truck, the two lights on the ceiling came on as is normal in cars, but when i turned the truck off and opened the door to exit, the lights did. Getting pretty frustrated with this np263 4×4 system in my ’03 2500hd.
