2. Issues with the Wiper Linkages: The wiper linkages connect the motor to the wiper blades. If they are damaged, bent, or disconnected, the wipers can stop working. Inspect the linkages and ensure they are properly connected.
3. Defective Wiper Switch: The wiper switch controls the wiper motor. If it's faulty, the wipers won't work. Try operating the switch to see if it responds.
4. Wiring Problems: Check the wiring connected to the wiper motor and the wiper switch for any loose, damaged, or corroded wires. Faulty wiring can prevent power from reaching the motor.
5. Fuse Issues: There could be a blown fuse in the fuse box related to the wiper system. Check the fuses and replace any blown ones.
6. Relay Malfunction: The wiper relay is responsible for controlling the power flow to the wiper motor. If the relay fails, the wipers won't work. Check the relay and replace it if necessary.
7. Faulty Control Module: Some vehicles have a control module that manages the wiper system. If the control module fails, it can affect the wiper operation. Check if your Exterra has a control module and troubleshoot it if necessary.
If you're unable to identify the cause of the issue, it's best to take your vehicle to a professional mechanic for further diagnosis and repair.
