Can anyone hear tell me if a dimmer switch for lights in a house can be used in a vehicle that uses a 12v system. I know that the switch is made for AC current so I'm not sure if DC will effect it in any way. I'm asking because the wiper switch on my truck doesn't work and I don't fell like digging through the harness to find the problem. If the switch would work it would give me a cheap solution to hopefully have variable speed wipers. I'm sort of thinking this won't work though and instead I'd need to use resistors to set different speeds.
Thanks in advance
