Either the motor has a short, or is seized, for some reason.
check fuses or relays
The fluid not spraying could be a clogged line or disconnected line or bad windshield washer motor. The rear wiper not working could be a bad wiper motor in the rear or unhooked linkage or fuse or relay. Check the fuses etc first.
The wiper arms have disconnected from the wiper motor. How do you reconnect them?
The wiper Motor is bad. Sorry
First check fuses, relays to wiper motor. Then check power to wiper motor. Then check linkage to wiper motor.
Disconnected or broken control linkage? Bad wiper transmission?
Check fuses and relays
It could be a faulty wiper Motor or short circuit in wiring related to wipers.
the relay is part of the wiper motor assembly. if the fuses are good, and there is voltage at the motor, then you must replace the motor
bad wiper switch Or, if you are certain the motor is running, the linkage could have become disconnected.
Broken or disconnected wiper transmission (linkage)?
Depending on the year, the wiper motor could be under the cowling or on the firewall. The firewall motor simply unbolts and is removed after the wires and linkage are removed. The cowling motor has to have the cowling removed first, then the wires and linkage are disconnected and the motor unbolted for removal.
