Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or hood.
Remove the cover and locate the power window fuse.
Use a fuse puller or pliers to remove the fuse and inspect it for continuity.
If blown, replace with a new fuse of the same amperage (typically 30A for power windows).

3. Replace Master Window Switch

Remove the driver’s side door panel using a trim removal tool, starting from the bottom and working around.
Disconnect the wiring harness from the master window switch.
Remove the screws holding the switch in place and lift it out.
Install the new master window switch by reversing the removal process.

4. Test and Replace Window Motors (if necessary)

If the windows still do not operate after replacing the switch, access the window motor by removing the door panel.
Disconnect the wiring harness from the window motor.
Use a multimeter to test for voltage at the motor terminals while pressing the window switch.
If there is voltage but the motor does not operate, replace the window motor.
To replace, remove the motor bolts and detach it from the regulator. Install the new motor and reassemble the door.
