Symptoms and warning signs

Identifying the specific behavior of your malfunctioning wipers can greatly assist in narrowing down the potential cause. Drivers often report a range of symptoms when their 2019 Toyota Highlander's windshield wipers are not working properly:

• Complete lack of operation: Wipers do not move at all, regardless of the switch position, even when trying the 'mist' function.
• Stuck in one position: Wipers stop mid-sweep or at the bottom of the windshield and won't move further, potentially blocking vision.
• Only one speed works: Wipers only operate on high, low, or intermittent, but not all settings, indicating a partial electrical failure.
• Slow or sluggish movement: Wipers move noticeably slower than usual, struggling to clear the glass, which can be a sign of a failing motor or binding linkage.
• Delayed response: There's a noticeable lag between activating the switch and the wipers beginning to move, suggesting an electrical or switch issue.
• Intermittent operation: Wipers work sometimes, then stop unexpectedly, or work for a few cycles and then quit, often pointing to loose connections or a failing component.
• Noise from the wiper motor area: A grinding, buzzing, or clicking sound may indicate a struggling or failing motor or a seized mechanical linkage.
• Only one wiper moves: One wiper arm works while the other remains stationary, almost always indicating a broken or detached wiper linkage.

How to verify and confirm the issue

Before diving into complex diagnostics, perform a few simple checks to confirm the nature of the problem with your 2019 Toyota Highlander's windshield wipers:

• Check the wiper switch/stalk: With the ignition on, cycle through all wiper settings (intermittent, low, high, mist) to see if any position elicits a response. Also, try the rear wiper if your Highlander is equipped with one, as it might share some electrical components or fuses.
• Listen for the motor: With the ignition on and the wiper switch activated, listen closely near the base of the windshield for any sound from the wiper motor. A humming or buzzing sound without movement could indicate a seized motor or disconnected linkage, while complete silence suggests a lack of power.
• Visual inspection of wiper arms and linkage: Gently try to move the wiper arms by hand. If they feel excessively loose or one moves independently of the other with little resistance, there might be an issue with the linkage connecting them. Also, look for any visible obstructions like leaves, ice, or debris at the base of the windshield that could be binding the mechanism.
• Check the fuse: Locate your Highlander's fuse box (typically under the hood and/or inside the cabin, often near the driver's footwell). Consult your owner's manual to identify the specific fuse for the windshield wipers (often labeled "WIPER" or "WSH"). Visually inspect the fuse for a broken filament. You can also test it with a multimeter for continuity, which is a more reliable method.
• Scan for diagnostic trouble codes (DTCs): While not always present for purely mechanical failures, an advanced OBD-II scanner can sometimes reveal codes related to the body control module (BCM) or other electrical systems that control the wipers. Even if no specific wiper code is present, general electrical fault codes can point to system-wide issues affecting multiple components.

Common causes (most likely first)

Several components can cause your 2019 Toyota Highlander's windshield wipers to stop working. Here are the most common culprits, ordered from most to least likely:

• Blown fuse: The most frequent and easiest fix. A power surge, a short circuit, or an overloaded motor can cause the fuse to blow, cutting power to the entire wiper system.
• Faulty wiper motor: Over time, the electric motor that drives the wipers can wear out, seize, or develop internal electrical faults. This is a strong possibility if you hear a humming sound but no movement from the wiper arms.
• Wiper linkage/transmission failure: The mechanical linkage (sometimes called the transmission) connects the wiper motor to the wiper arms, translating the motor's rotary motion into a sweeping action. These plastic or metal components can break, detach, or become corroded and seize, preventing the arms from moving properly.
• Defective wiper switch/stalk: The multi-function switch on your steering column controls the wiper speeds and functions. Internal electrical contacts can wear out or become corroded, leading to intermittent or complete failure of specific speeds or all functions.
• Wiring issues: Damaged, corroded, or disconnected wiring between the fuse box, switch, motor, or ground can interrupt the electrical circuit, preventing power from reaching the motor or signals from the switch.
• Faulty wiper relay: Some wiper systems use a relay to switch power to the motor. A stuck open or failed relay can prevent the motor from receiving power, while a stuck closed relay could cause the wipers to run continuously.
• Body Control Module (BCM) fault: The BCM manages many electrical functions, including wipers, in modern vehicles. While less common, a BCM malfunction can disrupt wiper operation. This is usually accompanied by other electrical issues across the vehicle.

Step-by-step diagnosis and fixes

Follow these steps to diagnose and potentially fix your 2019 Toyota Highlander's windshield wipers:

1. Check and replace the fuse: Always start here. Locate the wiper fuse using your owner's manual. If the fuse is blown (broken filament), replace it with one of the same amperage. If it blows again immediately, there's a short circuit or an overloaded component (like a failing motor) that needs further investigation.
2. Inspect wiper arms and linkage: With the ignition off, lift the wiper arms away from the windshield. Try to move them manually. If they feel loose or disconnected, the linkage might be broken or detached. Carefully remove the plastic cowl covering the wiper mechanism (refer to your Highlander's service manual for specific steps) and inspect the linkage for damage or disconnections. Reattach or replace as necessary.
3. Test the wiper motor: If the fuse is good and the linkage appears intact, the motor is the next suspect. You can often test the motor by disconnecting its electrical connector and applying 12V directly from the battery (with appropriate safety precautions and knowledge of wiring polarity). If the motor operates, the problem lies upstream (switch, relay, wiring). If it doesn't, the motor is likely faulty. This often requires removing the motor for access.
4. Test the wiper switch: Use a multimeter to check for continuity across the switch terminals in different positions. This can be complex without a wiring diagram, but it can confirm if the switch is sending the correct signals for each speed setting.
5. Check wiring and connectors: Visually inspect all wiring harnesses and connectors leading to the wiper motor and switch for signs of corrosion, fraying, or damage. Pay close attention to ground connections. Ensure all connections are secure and clean.
6. Replace components as needed: Based on your diagnosis, replace the faulty component (fuse, motor, linkage, switch, or relay). When replacing parts, always opt for OEM or high-quality aftermarket parts to ensure compatibility and longevity. For a wide range of parts and guides, explore our All repair guides.
