2020 Toyota Highlander Windshield Wiper Motor Replacement Cost

Windshield wiper motors are diagnosed by a guided process of elimination, from most likely, to least likely. The fuses are checked first, then the power at the windshield wiper switch, then power coming from the switch, to the wiper motor. If there is electrical power going to the windshield wiper switch, but the switch will not send power to the windshield wiper motor, the switch or wiring must be replaced. If the switch sends power, but the windshield wiper motor will not run, power at the windshield wiper motor would be checked. If electrical power reached the windshield wiper motor, but the motor did not run, it would be bench-tested, and confirmed failed.

Once access is gained, the servicing technician will being disconnecting the windshield wiper motor from the windshield wiper are linkages/rods. The windshield wiper motor is able to lift out once disconnected. Installation is the reverse of removal, and the wiper arms, and wiper blades should be inspected for condition, and function.

Windshield wiper motors for the most common vehicles are typically available from the aftermarket at a discount from the manufacturer price, but should be guaranteed to meet or exceed OEM standards if used. Many low-production, specialty, or luxury vehicles may require the windshield wiper motor to be purchased from the dealership, as the aftermarket may not invest in reproduction of parts for specific applications.

In most cases, a technician will charge a diagnostics fee for testing the system, and determining the wiper motor is faulty. This protects the customer from needlessly replacing a properly functioning component.

When the windshield wipers stop clearing the windshield, you may decide to replace the motor at home. This can be done without too much complication, and just a few hand-tools. The motor is normally tucked away underneath the cowl, but there is always a way to gain access. If you cannot gain access, or figure out how to get the motor out of the vehicle, take the vehicle to a professional technician to ensure the job is completed correctly.
