my Volkswagen Tiguan's windshield wipers are not working properly what could be wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery to ensure safety.

2. Inspect and Test the Wiper Switch

• Remove the steering column cover to access the wiper switch.
• Use a multimeter to test for continuity when the switch is activated.
• If faulty, replace the wiper switch.

3. Check and Replace the Wiper Fuse

• Locate the fuse box, usually found under the dash or in the engine compartment.
• Refer to the owner's manual for the specific wiper fuse location.
• Remove the fuse and check for continuity. Replace with the same amperage fuse if blown.

4. Inspect and Test the Wiper Motor

• Remove the wiper arms by undoing the retaining nuts using a socket set.
• Disconnect the wiring harness from the wiper motor.
• Apply direct battery voltage to the motor terminals to check for operation.
• If the motor does not run, it should be replaced.

5. Check the Wiper Linkage

• Inspect the linkage connected to the wiper motor for any wear or binding.
• Apply lubricant to any moving parts if there is binding.
• Replace the wiper linkage if damaged.
