Ok,
But if the resistor (connection) is in series with the wiper motor, and
the wiper motor draws a constant amount of current, then won't
increasing the resistance result in a higher current draw through the
whole circuit (since the wiper motor still draws the same amount of
current across it's connections)?
I've seen bad wiper motor connections cause fuses to blow. Maybe it's a
violation of Ohms law, but it's worth looking at.

As far as I can tell, yes--there will be a voltage drop across the
added resistance (which will generate heat in and of itself), and in
accordance with that P=IV law, a device that's going to use a
constant amount of power will have to draw more current through the
circuit to get that amount of power out of the lower voltage it will
see as a result of the voltage drop over the added resistance.
