Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the power windows using the fuse diagram.
Remove the fuse with a fuse puller and inspect it.
- If blown: Replace with a fuse of the same amperage rating.
- If intact: Proceed to check the switch.

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the window switch connector.
Test the switch with a multimeter to check for continuity.
- If faulty: Replace with a new switch.
Reconnect the switch and reassemble the door panel.

4. Inspect and Replace Window Regulator/Motor

With the door panel removed, inspect the window regulator for any physical damage.
Disconnect the window motor from the regulator.
Test the motor directly with battery voltage; if it does not work, replace the motor.
To replace the window regulator:
1. Remove any screws or clips securing the regulator.
2. Carefully pull out the old regulator.
3. Install the new regulator by reversing the removal steps.
Reconnect the window motor to the new regulator.
