Important safety information - read before proceeding

•Disconnect battery before working on electrical components to avoid shorts.
•Allow the engine to cool before working near the wiper motor.

Symptoms

•Windshield wipers do not operate on low speed
•Windshield wipers do not operate on high speed
•Intermittent wiper function works inconsistently
•Wiper motor makes unusual noises when activated
•Dashboard warning light may illuminate

Diagnostic Steps

1
Check the wiper switch function by operating the wipers through all speed settings.
2
Use an OBD-II scanner to check for any fault codes related to the wiper system.
3
Inspect the wiper motor and wiring for any visible signs of damage or corrosion.
4
Test the wiper motor with a multimeter to ensure it receives proper voltage at different speed settings.
5
Verify the condition of the wiper relay by swapping it with a similar relay from the vehicle.
6
Check for any blown fuses in the wiper circuit.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the vehicle is in a safe, stable position (preferably on flat ground).

2. Remove the Wiper Arm

Use a wiper arm puller tool to carefully detach the wiper arms from the splines on the motor shaft.
Loosen the nut holding the wiper arm using a socket wrench, then remove the wiper arm.

3. Access the Wiper Motor

Remove the plastic cowl cover by unscrewing any fasteners and unclipping it from the windshield.
Locate the wiper motor assembly.

4. Inspect and Test the Wiper Motor

Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the motor connector while activating the wiper switch on different settings.
- Expected voltage should be close to battery voltage (12V) when activated.
If voltage is present but the motor does not operate, it may need replacement.

5. Replace the Wiper Motor (if necessary)

Remove the wiper motor mounting bolts using a socket set.
Carefully detach the motor from the linkage.
Install the new wiper motor by reversing the removal steps, ensuring proper alignment.
Torque the mounting bolts to manufacturer specifications.

6. Reassemble and Test

Reconnect the electrical connector and reattach the cowl cover.
Reinstall the wiper arms back onto their splines, ensuring correct alignment.
Reconnect the vehicle battery and test the wipers through all speeds.
