Solution

1. Preparation

Gather necessary tools: multimeter, fuse puller, screwdrivers, and a wiring diagram if available.
Disconnect the negative battery terminal to prevent any electrical shorts during the repair.

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller.
Inspect the fuse; replace it if blown with an identical amperage fuse.

3. Test Power Window Switch

Reconnect the negative battery terminal.
Use a multimeter to test for voltage at the power window switch.
- If voltage is present, proceed to check the window motor.
- If no voltage, inspect wiring to the switch for damage or loose connections.

4. Check Window Motor and Regulator

Remove the door panel using a screwdriver and trim removal tools.
Disconnect the window motor connector.
Use a multimeter to test for power at the window motor connector while pressing the window switch.
If power is present but the motor does not work, replace the window motor.
If no power, trace wiring back to the switch and repair any damage.

5. Reassemble

Reinstall the door panel securely, ensuring all clips and screws are in place.
Reconnect any connectors that were disconnected during the process.
