Good noonish time My issue is, I have a M1120A4 Light Hauling System (LHS). The issue is that the clearance and turn signal lights are flashing when the Hazard switch is on. I have already changed out the wiring on the steering wheel. That's where I thought the issue was. Nope. it's something else. Any help would be appreciated . Thanks Towbarman
Pull one turn signal bulb at a time. The easiest place to start is a shorted bulb/ socket.
My mechanic told me more on the problem. Left blinker on all lights are going, clearance and turn signal lights. Turn right turn signal on no problem with lights flashing
Sounds like a ground problem, at least thats the first place I'd look.
Or if sealed beam lights a broken filament.
Do you have a trailer plug? They tend to corrode and stray voltage will cross wires through the corrosion.
