This can be done by holding the window switch in the up position for a few seconds after the window is fully closed. Then, release the switch and press it again to close the window automatically.
3. Inspect the Window Track: If you suspect that the window may be off track, you will need to remove the door panel and examine the track. Look for any signs of damage or misalignment. If necessary, realign the window and repair any broken tracks or components.
4. Check the Window Motor: If the power window motor is not functioning, you may need to replace it. Use a voltmeter to verify if the motor is receiving power. If it is, but the window is still not working, the motor may be faulty and require replacement.
5. Inspect the Window Switch and Wiring: Check the window switch for any signs of damage or malfunction. If the switch is not working properly, it may need to be replaced. Additionally, inspect the wiring for any loose connections or damage. Repair or replace any faulty wiring as needed.
If these troubleshooting steps do not resolve the issue, it may be best to consult a professional mechanic or contact a Toyota dealership for further assistance.
