Solution

1. Preparation

Tools Required: Flat screwdriver, multimeter, socket set, wrenches
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface with the wipers in the "off" position.

2. Inspect and Test the Wiper Motor

Sub-steps:
1. Remove the wiper arms by loosening the retaining nut with a socket wrench and carefully lifting the arms off the spindle.
2. Unplug the electrical connector from the wiper motor.
3. Using a multimeter, check for voltage at the motor connector while activating the wiper switch. If there is no power, further diagnose the switch or wiring.
4. If power is present, connect the motor directly to a 12V battery to test its operation.

3. Replace the Wiper Motor (if necessary)

Sub-steps:
1. If the wiper motor fails the direct power test, remove the mounting bolts securing the motor using a socket set.
2. Take out the old wiper motor and replace it with a new one.
3. Reconnect the electrical harness and secure the motor with mounting bolts to the specified torque (usually around 8-12 ft-lbs, check manufacturer specifications).

4. Inspect and Repair Wiper Control Switch (if necessary)

Sub-steps:
1. Remove the steering column covers using a flat screwdriver.
2. Disconnect the wiring harness from the wiper control switch.
3. Test the switch with a multimeter for continuity when engaged.
4. If defective, replace the switch and reconnect the wiring harness.

5. Reassemble and Test

Reinstall the wiper arms, ensuring they are positioned correctly.
Reconnect the negative battery terminal.
Test the wiper system to ensure proper operation.
