67 barracuda rear lights stay on
In addition to above, could be a few things. Rust, corrosion, malfeasance under there in the pedal hangers, the master, etc.
Bad/ misadjusted switch
BUT BUT DAMMMIT BUT................the switch hanging up should not cause any wiring to get hot. CHECK the bulkhead connector for poor connections. Something is generating that heat
I just HATE malfeasance..................
