Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the engine compartment.
2. Identify the power window fuse using the diagram on the fuse box cover.
3. Remove the fuse using a fuse puller and inspect it for continuity.
4. If blown, replace it with a fuse of the same amperage.

3. Test and Replace Window Switches

Sub-steps:
1. Remove the door panel using a trim removal tool.
2. Disconnect the electrical connector from the window switch.
3. Use a multimeter to test for continuity across the switch terminals.
4. If the switch is faulty, replace it with a new switch by reversing the disassembly steps.

4. Inspect and Replace Window Motor

Sub-steps:
1. If the switch is functional, locate the window motor by removing the door panel.
2. Disconnect the motor's electrical connector.
3. Use a multimeter to check for voltage when the switch is activated.
4. If there is voltage but the motor does not operate, remove the motor by unscrewing it from the regulator.
5. Install the new window motor and reassemble the door panel.

5. Reconnect Battery and Test

Sub-steps:
1. Reconnect the vehicle battery.
