Disconnect the electrical connector from the switch.
Install the new switch by connecting the electrical connector and securing it into the door panel.
Reassemble the door panel.

4. Replace Power Window Motor (if necessary)

Remove the door panel and insulation to access the window motor.
Disconnect the window motor from the wiring harness.
Unbolt the motor from the regulator assembly.
Install the new motor by securing it with bolts and reconnecting the wiring harness.
Reassemble the door panel.

5. Test Window Operation

Reconnect the negative battery terminal.
Test the power window operation with the switches to ensure proper functionality.
