The passenger side windshield wiper has quit working.The driver side still works.

Maybe the nut that hold the wiper to the linkage is either loose or stripped? The linkage itself is bad?

I think your wiper motor is fine because the passenger side works and uses the same motor to move the wipers.

If it were the motor neither side would move. Chances are its the linkage.
You'll probably need to remove the panel under the windshield to access the linkage and check it out.

arm/linkage came loose.. its at the base of the windshield..

Either the wiper arms are loose or stripped on the pivots or the wiper linkage is broken. Try tightening the arm to pivot bolt. If that doesn't work, remove the plastic cowling and examine the linkage. You can buy new linkage for it.

sounds like the connecting rod between both wiper arms either broke or one of the keepers popped off under the connector for that arm..since the wiper system IS NOT designed to wisk snow off the window once accumulated, this can an does happen.. even seen motors get burned out doing this..cleaning the window first will save this issue and the equiptment. need to acess this arm<take off the vented peice below the windshield and everything should be visible there..repost findings

there is 2 wiper motors . 1 for the drivres side and the other for the passenger. sounds like a bad passenger side motor

First remove the complete passenger side wiper check and make sure splines on wiper are not stripped. If this is not the problem It could be a linkage bar from the wiper motor to the wiper off or disconected. Since both wipers share the same motor if one works the other should. Check this by removing both wipers and then "Cawl" (little black piece between the hood and windshield underneath the wipers) Underneath the cawl you should be able to see the windshield wiper motor, and linkage bar to both of the wipers. See if the bar is disconected from the passenger side. If it is than reconnect it. These are the only two possible scenarios.

you should be able to see the wiper trans.through the grill between the blades to see if it'sbroken or one side has comeoff

There is a bar that connects both your windshield wipers together check that to see if it is broke or has come unscrewed. Should be underneath the hood upagainst the firewall.

the linkage on the arms has broken.
