Solution

1. Preparation

Gather necessary tools and materials.
Disconnect the vehicle battery to ensure safety.
Tools required: Socket set, screwdriver set, multimeter, wire connectors.

2. Inspect and Replace Fuse

Locate the fuse box in the Tiguan (typically under the dashboard or in the engine compartment).
Identify the fuse related to the power windows using the fuse diagram.
Remove the fuse using a fuse puller and inspect for damage.
Replace the blown fuse with one of the same amperage rating (check owner's manual).
Reconnect the battery and test window operation.

3. Check and Repair Window Motor

Remove the door panel using a screwdriver and socket set.
Disconnect the wiring harness from the window motor.
Use a multimeter to check for voltage at the motor connector when the switch is activated.
If there is voltage and the motor does not operate, replace the window motor.
If there is no voltage, trace back to the switch and check for continuity or damage.

4. Inspect Window Regulator

If the motor is functioning, inspect the window regulator mechanism for damage or binding.
Remove the window from the regulator if necessary to check for smooth operation.
Clean and lubricate the regulator components if they are obstructed.
Replace the window regulator if it is damaged or not functioning properly.
