Solution

Problem Diagnosis: Non-Functioning Windshield Wipers on Toyota Camry XV70

Step 1: Visual Inspection

Check Wiper Blades: Inspect the wiper blades for wear, damage, or debris. Look for tears or hardening of the rubber.
Check Wiper Arm Position: Ensure that the wiper arms are not bent or broken and are correctly positioned on the windshield.

Step 2: Electrical System Check

Fuses: Locate the fuse box (refer to the owner’s manual for the exact location) and check the wiper fuse for continuity.
Wiper Switch: Verify that the wiper switch is functioning properly by toggling between settings (off, low, high, and intermittent) and listening for any clicks or changes in functionality.

Step 3: Power Supply Check

Multimeter: Use a multimeter to check for voltage at the wiper motor connector. With the wiper switch in the "on" position, you should see approximately 12 volts at the connector.
Ground Connection: Inspect the ground wire for continuity and proper connection.

Step 4: Wiper Motor Functionality

Direct Power Test: If voltage is present at the connector, directly connect the wiper motor to a known good power source (12V battery) to see if the motor functions. If it operates, the issue may be upstream (wiper switch or wiring).

Repair Instructions

Repairing/Replacing Wiper Blades

Remove the Old Wiper Blades:
- Lift the wiper arm away from the windshield.
- Press the tab on the wiper blade connector and slide the blade off the arm.
Install New Wiper Blades:
- Align the new wiper blade with the arm and slide it into place until it clicks.
- Lower the wiper arm gently back onto the windshield.

Replacing the Wiper Fuse

Locate the Fuse Box:
- Refer to the owner’s manual to find the fuse box location.
Remove the Fuse:
- Use the fuse puller or pliers to remove the wiper fuse.
- Inspect the fuse for a broken filament.
Install New Fuse:
- Insert a new fuse of the same amperage rating into the fuse slot.
- Recheck the operation of the wipers.

Replacing or Repairing the Wiper Motor

Access the Wiper Motor:
- Remove the plastic cover under the windshield (if applicable) by unscrewing it.
- Disconnect the electrical connector from the wiper motor.
Remove the Wiper Motor:
- Unscrew the mounting bolts holding the motor in place.
- Carefully pull the motor out of its housing.
Install New Wiper Motor:
- Position the new wiper motor, secure it with bolts, and reconnect the electrical connector.
- Test the wipers before reassembling the plastic cover.

Final Testing

After performing repairs, turn on the ignition and test the wipers through all settings.
Ensure that the wipers operate smoothly without any obstruction or unusual noise.
Check for proper alignment and contact with the windshield.

Conclusion

If the wipers are still not functioning properly after conducting the above steps, further investigation into the wiring harness or consulting with a professional technician may be necessary.
