First make a couple of short lead wires by stripping both ends. put one end of each wire through the two outside terminals of the plug on the motor. these are terminals 1& 3 shown in the diagram. make a third such lead wire that is connected to the middle terminal 2. now hook your battery charger to the motor as follows; hook the positive clip. The 64 supplement has both a chapter on the wiper motor and a wiring diagram that includes the wiper circuit. main thing to remember about these wiper circuits that seems backwards to most of us is that the switch on the dash controls the ground side to the wiper motor and that the motor always has 12 volts when the ignition switch is on. eric. The gm wiper motor is controlled by a switch on the dash, which sends power to the motor through a series of wires. the motor itself has two wires coming out of it: one is positive, and the other is negative. the positive wire goes to the switch on the dash, and the negative wire goes to ground. when the switch is turned on, power flows from.

If it has four terminals then the top two are connected together. do not mistake the connections for the washer pump. you need to jumper 12vdc to the top terminal and ground to the bottom terminal. the wiper motor should run. if you move the ground jumper from the bottom terminal to the next one higher, the wiper motor will change speed. As a final piece of the puzzle, on many gm wiper motors, the gear box also ran piston style washer pump driven by the wiper motor. to use the pump, a solenoid in the motor cover engages a four lobe cam that drives the pump piston. of course, the el camino also used this feature.
