Wipers work backwards from most circuits. There is always positive 12 volts
to the wiper motor as soon as the ignition is turned on. The switch then
creates the ground when turned on. It sounds as though there is a short to
ground somewhere before it gets to the wiper motor. Try unplugging all the
wiring at the wiper motor and see if it still blows the fuse. If so, there
is a short before the wiper motor, most likely where it passes through the
firewall.

Guys,
I have a brand-new Painless Performance wiring harness, new windshield
wiper
motor, new washer pump, and new wiper switch. When I try to use the
wipers,
the 15A fuse blows in the fuse panel. I can hear it go each time I turn
on
the ignition.
My headlights work (including high-low beam switch), my turn signals work,
my brake lights work, but my wipers are toast. I'm trying to get the car
inspected, and this is really holding me up.
Does the fact that the fuse gets blown mean that the wiring harness is
supplying more amperage than the motor requires, or is it the other way
around (the motor is demanding more current than the harness is
supplying)?
Thanks,
Bobby
