Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repair.

2. Inspect and Replace Fuse

Locate the fuse box for the power windows.
Remove the fuse related to the power windows and inspect it for continuity.
- Tools Required: Fuse puller or needle-nose pliers
If the fuse is blown, replace it with a fuse of the same amperage rating (typically 20A).

3. Test and Replace Window Motor

If the fuse is intact, proceed to the window motor.
Remove the door panel using a socket set to access the window motor.
- Tools Required: Socket set, trim removal tool
Disconnect the motor connector and apply direct voltage from a battery.
- Warning: Ensure polarity is correct to prevent motor damage.
- If the motor operates, clean the connections and reinstall. If it does not, replace the motor.

4. Inspect Master Window Switch

Remove the master window switch from the door panel.
Use a multimeter to check for continuity on the switch terminals.
If continuity is not present, replace the master window switch.

5. Reassemble and Test

Reinstall the door panel and ensure all clips and screws are secured.
Reconnect the negative battery terminal.
Test the power windows to confirm functionality.
