windshield wiper stopped working

It sounds like the wiper arm has come lose. Can you check the arm nut to make sure it is tight?

Check out the diagrams (Below)

Please let us know what you find.

Yep that was the problem all right the spline was a little messed up but one it was tight everything worked great! I love this site

When you turn them off they park in the up position? If so, you have an issue with the park arm on the wiper motor. There is a little tab where it meets with the wiper transmission that has probably bent. It will be will need to be realigned.

Hi, my left windshield wiper has stopped working the right one still works. the left one starts to go up and stops and goes back down. how can i get it to start to work again?

Locate at the bottom of the wiper arm is a nut it may be covered by plastic
adjust where it need to be and tighten the nut.

wipers straight up and down when turned off.work fine when using. had snow accumulation when shut off before the wipers got off track

Snow in the path of the wiper arms can damage the splines of the arms. I would grab each arm and see if you can manually rotate it on the pivot. If you can, you need arms. If not, you may be able to loosen them at the pivots, make sure the system is off and parked, place the arms in true park position and tighten or install them.

Drivers side wiper does not work--passenger side ok. Think wife tried to run wipers and they were frozen under ice.

Remove plastic cap at base and check that nut is tight.

That fixed the problem--Thanks for your help

Your welcome.
