my Toyota Corolla E170 (2013-2019) wipers won't turn on what should I check

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Tools Required:
  • Socket set
  • Multimeter
  • OBD-II scanner
  • Screwdriver set

2. Check and Replace Wiper Fuse

• Locate the fuse box (typically under the dashboard or in the engine bay).
• Remove the cover and find the wiper fuse (refer to the diagram on the cover).
• Use a fuse puller or pliers to remove the fuse and check if it's blown (a broken filament indicates a blown fuse).
• If necessary, replace the fuse with the same amperage rating.

3. Inspect and Test Wiper Motor

• Remove the wiper arms using a wiper arm puller if needed.
• Disconnect the wiring harness from the wiper motor.
• Use a multimeter to check for voltage at the connector when the wiper switch is activated.
• If voltage is present and the motor does not operate, replace the wiper motor.

4. Reassemble and Test

• Reconnect all wiring harnesses and reinstall the wiper arms in the correct position.
• Reconnect the negative battery terminal.
• Test the wipers to ensure they operate correctly.
