wiper motor for 71?

brandon11130 · Apr 15, 2007

i think i blew my jeeps wiper motor. where can i buy a replacment? is it the same as the one used in 76+ cj's? is the linkage the same?

my jeep was missing part of the linkage so i tried to fab somthing out of stock and i think i made it slightly too long and the motor seized up halfway through the rotation.

I made these notes when I swapped an intermediate w/s onto my Jeep:

The 4WD vendors will have a motor for ‘68-’75, and one for ‘76-’83. Both motors are a 2-speed, self-park, 3-wire plug, and the only difference is in the location of the mounting bracket at the end of the motor. The early version will have the bracket centered on the motor body, the later version has a hole that’s offset from the body. The later version usually sells $12 - $15 cheaper. eBay had the best prices that I could find.

mine had 3 wires coming out of it, but only 2 did anything, one was slow and the other was fast. what is the other supposed to do?

well turns out the motor is fine, i just killed the crappy battery i was using when it was messing with it. now that i dont need the motor whats the best place to find the linkage, i need the peice from the motor to the first wiper.

does anyone have one laying around that they could measure the total length for me and also from the center of the drilled hole to the other hole.

and one last question. what was used to hold the linkage in place, i bought some little hitch pins but they only work on the motor side, did the factory use somthing more like a C to hold it in?

A post I saved - not sure who the author was:

The three wires are for the high, low, and park. Black is park, green is low speed and red is high speed. When the 12 volts is removed from high or low, the 12 volts that is always connected to the park wire will cause the motor to continue to run until it reaches the park position. At that time a cam inside the motor assembly will disconnect the park wire from the motor and everything stops.

You’ll want to connect 12 volts to the park wire all the time, even with the wiper switch off. Then, if you also connect the 12 volts to either of the other two wires, the wiper will run. If you remove the 12 volts to the wire, the motor should continue to run until it reaches the park position at which time it will shut off.
