Tools Required: Small flathead screwdriver, contact cleaner
Remove the switch panel using a flathead screwdriver carefully to avoid damaging the trim.
Disconnect the electrical connector from the window switch.
Clean the connectors and switch terminals with contact cleaner to remove any corrosion or dirt.
Reconnect the window switch and reassemble the panel.

4. Inspect Wiring and Connections

Tools Required: Multimeter, wire strippers
Inspect the wiring harness leading to the window motor for any visible damage or disconnections.
Use a multimeter to test for continuity in the wires.
Repair or replace any damaged wiring as necessary.
