Re: Cheapest and easiest way to slow down a motor
The wipers have resistors for the different speeds. If equipped with intermitent wipers (almost all vehicles these days) then there's also a timer, this is what greencactus was mentioning.
Depending on the vehicle the resistors and timer can be part of the switch, a separate unit somewhere, or part of the wiper motor. My 1987 Chevy Caprice has a circuit board mounted to the wiper motor where all this is.
The blower motor (for heat, defrost, a/c) for a vehicle also uses resistors to get the different speeds. These resistors would be attached to a single board in the heater box. They are in the heater box to help keep them cool with the moving air.
