1992 Nissan Maxima windshield wipers

The ball socket in the linkage has probably popped off of the shaft on the motor.

They do that incase you leave you wipers on when you turn off your car and then the wipers freeze to the window over night.

You have to take the cowling off that is at the base of the window to get to it.

Be prepaired to have to buy a new linkage arm.
The plastic ball socket break most of the time when that happens.
Most Nissan dealers keep them instock.
