Here's a link to a build-it-yourself CURRENT limiter. Will slow the motor down to safe speeds without the excessive heat side effect (this one would be warm, not HOT):

If using the voltage dropping resistor method be sure he mounts it in a place that gets PLENTY of air flow and not next to any paint you don't want blistered from the heat.You can probably order a 12V rotor to fit in your wiper motor body.
