For a few weeks I am borrowing a Chevy Silverado truck whose high beam lights are not working and I’d like to take a try at fixing it. In old cars you could just follow wires and know where the problem was but I have no idea how things might work now with all those computers and stuff. Is this something I can take a stab at or am I better off taking it to a shop (or just returning the truck as it is)?
The blue indicator on the panel lights up but none of the headlights do. This leads me to believe it is not that the filaments are all out but rather that the cause lies elsewhere.
