Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Tools required: socket set, multimeter, flat-head screwdriver, Torx bit set.

2. Remove the Wiper Arm

Use a flat-head screwdriver to gently pry off the plastic cover at the base of the wiper arm.
Use a socket set to remove the nut securing the wiper arm to the motor shaft.
Carefully pull the wiper arm off the shaft; if it's stuck, use a wiper arm puller.

3. Access the Wiper Motor

Remove the trim panel located under the windshield if necessary, using the appropriate Torx bits.
Locate the wiper motor and disconnect the electrical connector carefully.

4. Inspect and Test the Wiper Motor

Using a multimeter, check for voltage at the wiper motor connector while activating the wiper switch.
If voltage is present but the motor does not run, the wiper motor may need replacement.
If no voltage is present, further inspect the wiper switch and relay.

5. Replace the Wiper Motor (if necessary)

Remove the bolts securing the wiper motor to the vehicle chassis.
Replace the old motor with a new one, ensuring it is properly aligned.
Reattach the electrical connector and secure the motor with bolts.

6. Reassemble Components

Reattach the wiper arm to the motor shaft, ensuring it is firmly secured.
Replace the trim panel under the windshield.
Reconnect the vehicle battery.
