Fixing Windshield Wipers Not Working on a 2022 Toyota Highlander

Tools Required

Multimeter
Fuse puller
Screwdriver set (Philips and flathead)
Socket set
Pliers
Replacement fuses and/or relays (if necessary)
Wiper motor replacement (if needed)

Repair Instructions

Step 1: Check the Wiper Switch

Action: Turn the wiper switch through all settings.
Expected Result: If the wipers move, the switch is functioning correctly. If not, proceed to the next step.

Step 2: Inspect Fuses

Action:
1. Locate the fuse box under the driver's side dashboard or under the hood.
2. Remove the cover and find the wiper fuse (refer to the diagram on the fuse box cover).
3. Use a fuse puller to remove the fuse.
4. Inspect the fuse for a broken filament.
Expected Result: If the fuse is blown, replace it with a new one of the same amperage. If not, continue to the next step.

Step 3: Test the Wiper Relay

Action:
1. Locate the wiper relay in the fuse box (consult the owner’s manual for exact location).
2. Carefully remove the relay.
3. Swap it with another relay of the same type to check if the wipers start working.
Expected Result: If swapping the relay resolves the issue, replace the faulty relay.

Step 4: Inspect the Wiper Motor

Action:
1. If the wipers still do not work, check the wiper motor.
2. Remove the wiper arms (use a flathead screwdriver to gently pry them off the splines if needed).
3. Remove the wiper motor cover (usually requires a socket set).
4. Check for any visible damage or corrosion.
5. Using a multimeter, check for voltage at the motor connector when the wipers are activated.
Expected Result: If there is no voltage, the wiring or switch may be faulty. If there is voltage but the motor doesn't operate, replace the wiper motor.

Step 5: Inspect Wiring and Linkage

Action:
1. Check the wiring harness for any visible issues like frays or disconnections.
2. Inspect the mechanical linkage connecting the wiper motor to the wiper arms.
3. Ensure everything is connected and there are no obstructions.
Expected Result: Repair any damaged wiring or linkage as necessary.

Conclusion

After following these diagnostic steps and repairs, reassemble any components removed. Test the wipers to ensure they function correctly across all settings. If issues persist even after completing these steps, further inspection may be required or consider consulting with a professional technician.
