Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, screwdriver set, socket set, wiring repair kit.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Replace Fuses
  • Locate the fuse box, usually found under the dashboard or in the engine compartment.
  • Identify the fuse for the power windows (refer to the owner's manual for the correct fuse number).
  • Remove the fuse using a fuse puller and inspect it. If blown, replace with a new fuse of the same amperage.
3. Test and Replace the Window Switch
  • Remove the door panel to access the window switch.
  • Disconnect the switch connector and test it with the multimeter for continuity.
  • If faulty, replace the switch with a new one, ensuring proper fit.
4. Inspect and Repair Wiring
  • Visually inspect the wiring harness leading to the power window motor for damage or disconnections.
  • Repair any damaged wires using appropriate connectors and electrical tape.
  • Ensure all connections are secure.
5. Test Power Window Motor
  • With the door panel still removed, connect the multimeter to the power window motor connector.
  • Have an assistant press the window switch while you monitor the voltage. If voltage is present but the motor does not operate, the motor may need replacement.
  • If no voltage is detected, trace back to the switch and harness for further issues.
6. Replace Power Window Motor (if needed)
  • If the motor is determined to be faulty, remove any screws or bolts securing the motor in place.
  • Disconnect the motor's wiring harness and remove it from the window regulator assembly.
  • Install the new power window motor, reconnect the wiring, and secure it with screws or bolts.
