Q: Windshield wipers don't work

There are a couple possibilities. The electric wiper motor has failed or blew a fuse, or the problem is in the wiper transmission linkage. When the plastic parts of the transmission are worn, the linkage can come apart. Grab a wiper arm and try to move it up the windshield. If you can move it with light pressure and both wipers move in sync, the linkage arm popped off of the motor. If only one moves, any other joint came apart. If you can’t move either, the problem is the motor, or the wiring involved, fuse, switch, etc. No parts are available for the transmission. A good used one is your only option. New and remanufactured motors are also available. If you need assistance, have a certified mechanic inspect your windshield wipers and replace your wiper motor if needed.
