2002 Chevy Silverado V8 Four Wheel Drive Automatic 42,000 miles
2002 chevy silverado 1500HD 4x4 horns don't work. Checked fuse snd ok. Checked relay ok. Panic button on factory alarm will set off alarm and it seems to be flashing but no sound from horns. Anyone have an idea on what could be wrong. Am I missing something here? Only thing left I can see it might be is the horns it's self or I guess the switch in the steering wheel. Please, someone help me out. Also can anyone tell me where online I can get the wiring diagram for the 2002 chevy silverado 1500HD 4x4 for free?
