Solution
1. Preparation
  • Tools Required: Flathead screwdriver, Torx screwdriver set, multimeter, fuse puller.
  • Disconnect the negative battery terminal to ensure safety while working on electrical components.
  • Allow the vehicle to sit for a few minutes to discharge any residual electrical power.
2. Fuse Inspection
  • Locate the fuse box, typically found in the glove compartment or under the dashboard.
  • Remove the relevant fuses for the power windows using a fuse puller.
  • Inspect the fuses visually; if any are blown, replace them with fuses of the same amperage (specified in the owner's manual).
3. Switch and Wiring Check
  • Remove the door panel using a Torx screwdriver to access the window switch assembly.
  • Disconnect the wiring harness from the switches and test each switch with a multimeter to ensure proper continuity.
  • Inspect the wiring for any signs of wear or damage; repair or replace as necessary.
4. Window Motor Testing
  • Reconnect the power window switches.
  • Use a multimeter to measure voltage at the window motor terminals while pressing the window switch. Expect to see battery voltage (around 12V).
  • If voltage is present but the motor does not operate, remove the window motor for inspection.
5. Motor Repair or Replacement
  • If the motor is found to be faulty, remove it by unscrewing the retaining bolts and disconnecting the wiring harness.
  • Install the new or refurbished motor, ensuring it is properly aligned and secured.
  • Reconnect all electrical connectors and reassemble the door panel.
