Repair Instructions

1. Wipers Not Operating

Check Power Supply to Wiper Motor:
- Disconnect the wiper motor connector.
- Using a multimeter, check for voltage (generally should be around 12V).
- If no voltage is present, trace the wiring back to the fuse box and check the fuse (typically a 20A fuse in the fuse box).
Replace Wiper Motor:
- If power is supplied but the motor does not operate, replace the wiper motor.
- Remove the wiper arms by loosening the nut with a socket wrench.
- Remove the motor mounting bolts and disconnect the wiring harness.
- Install the new motor in reverse order.

2. Wipers Move Intermittently

Inspect and Replace Wiper Control Switch:
- Locate the wiper control switch on the steering column.
- Remove the steering column covers using a screwdriver.
- Test the switch for continuity with a multimeter; replace if faulty.

3. Wipers Streaking or Skipping

Replace Wiper Blades:
- Lift the wiper arms away from the windshield.
- Use a wiper blade removal tool to detach the old blades.
- Attach new wiper blades by aligning them with the connector and pushing until secure.
Check Wiper Arm Tension:
- Ensure the wiper arms are not bent and are applying adequate pressure on the windshield.
- Adjust the arm if necessary by gently bending it back to shape.

4. Wipers Making Noise

Lubricate the Linkage:
- Access the wiper motor and linkage assembly.
- Apply white lithium grease to all pivot points to reduce friction and noise.
Inspect for Damage:
- Look for any damaged or worn-out components in the linkage; replace if necessary.

5. Wipers Stuck in Up Position

Check Wiper Motor and Linkage:
- Inspect the wiper motor to ensure it is receiving power.
- Manually move the wipers to the resting position if necessary and then turn off the motor.
Reset Wiper Position:
- Once at the resting position, reattach the wiper arms and ensure they are aligned properly with the windshield.
