The switch could be “coming apart” with the bent over tabs stretched if it’s the type I think it is. Or the phenolic material cracked? That could cause possible hot to case or full 12 to motor through switch instead of the relay. Best to inspect at this time. Also you could watch exactly which positiin caused the fault so you can observe on bench.
