Wiper motor

My windshield wiper motor doesn’t work. Any one know how to test to see if it is the motor or the switch?

I have a 3-wire motor that has been changed in the past by the previous owner and it looks like he used a different switch than the factory, the connector wires are spliced in the middle.

So I guess what I looking for is to test the motor can I put the black wire to the - side on the battery and I think the other 2-wires are for slow and high speed to the positive side in order to test the motor?
One at a time of course?

Before you go blamin' the motor, take the linkage off the motor. That way you'll find out if the shafts are binding the linkage. Also, make sure you've got a good ground. Start there...

If the motor has black, green and red wires, the green is for low speed, red is for high speed and black returns it to park position. The case provides ground, and on old Jeeps, a poor ground is a common malady.

Motor is bad

I confermend today that the motor is bad, now will a 76 fit a 72 or do I have to stick with a 72 and below?

I am guessing that you have a CJ 5. The 1969-1975 are the same wiper, they mount bottom left on the outside. they changed in 1976 to inside.
So you will need the outside wiper for the 1972.

got it running

I got the motor running today but when the wipers went out to the far right it stopped.

Does the motor only run in one direction or two?

Or do I have to adjust the linnkage?

Motor runs one direction. On later CJs, after '76, it has a crank that connects to links that connect to arms on the back of the studs. There is no adjustment to the linkage. All you can do is put the wiper arms onto the studs in a different position. Did you take the motor off to work on it?

yea I took it off so I could take it to work to fix it. I was putting it in different positions a little while ago and now it don't move the wipers at all but when I take it back off the motor turns fine.

I dont know what position the wiper blades go during the install or which way the <swivel> goes up or down???

There should be a wire that parks the motor. It runs through a switch inside the motor that turns it off when it gets to the park position. Could you be using that one thinking it's the run wire?

Was the wiper motor bad? Did you actually replace the motor?

If the motor works when you take it off, and dies when connected to the linkage then look at the linkage. The linkage can bind and cause lots of problems. If it's binding it can bind to a point that the motor cannot overcome the bind, and stalls.
