Broken linkage? Disconeccted linkage? EDIT::: The most likely cause is a bad wiper control module, its attached to the wiper motor
motor is working but wiper blades do not move.
Ensure proper function of arms that connect motor to wiper blades. Also ensure there are no loose screws or any other obstructions that may block path of wiper arms.
The seat safety switch is not working properly correctly. If the safety does not sense that there is anyone on the seat then it will shut down the mower. This keeps the mower from running over someone if they would happen to fall off while mowing. Or if the safety is working you may have bad bearings on your deck and that will also stall your motor, or something jammed in the blades.
If the motor is turning, but the wipers are not moving, then you have a broken or disconnected linkage.
The fan blades are turned by an electrical motor.
Blown fuse, bad switch, defective blower motor, or bad HVAC resistor pack. Wet fish caught in fan blades??
Fans shaft and blades are attached to rotor shaft of the motor
no The tacho picks up pulses from the starter motor or ignition system.
Can be the fan motor is defective, thermal relay is bad, fuse blown, or loose connection.
bad wiper switch Or, if you are certain the motor is running, the linkage could have become disconnected.
The motor has a coil of wire that is an electromagnet. This causes the motor to spin, turning the fan blades.
Most likely it's the motor assembly. There is an internal switch that keeps the motor running until the wiper blades are in the "park" position. If the internal switch fails, the wiper will continue to run or will turn off wherever the blades are when you turn off the wipers. Either can happen when the wiper internal switch fails.
