Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Screwdriver set, multimeter, wire stripper/crimper, OBD-II scanner.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Test the Window Switch

Remove the door panel using a screwdriver to access the window switch.
Disconnect the window switch connector.
Use a multimeter to check for continuity in the switch. If defective, replace with a new switch.

3. Test the Window Motor

Locate the window motor within the door assembly.
Disconnect the motor from the wiring harness.
Use jumper wires to connect the motor directly to the battery, observing the polarity (positive to positive, negative to negative).
If the motor operates, it is functioning properly; if it does not, replace the window motor.

4. Check Wiring and Ground Connections

Inspect the wiring harness for any signs of fraying, cuts, or corrosion.
Ensure all connectors are securely attached.
Use a multimeter to check ground connections. Repair any faulty wiring as necessary.

5. Reassemble Components

If the issue is resolved and all components are in good condition, reattach the door panel.
Ensure all clips and screws are secured properly.
