Toyota Corolla Power Window Not Responding – Fuse o r Switch?

If your Corollas power window has stopped working completely and you’ve already checked the fuse, here are some steps to help you figure out whether the issue is with the switch, motor, o r something else:
1. Test the Switch:

Method: Try operating the power window from both the driver’s side and passenger’s side switches if applicable. If the window doesn’t work from either switch, the problem could be the switch itself.
What to Look For: If the switch feels “loose” o r you don’t hear any sound from the motor when you press it, it might be faulty.
Test Another Window: If you have other working windows, try swapping the switch with one of them. If the window works after swapping switches, then the issue is with the original switch.

2. Listen for Motor Sounds:

Method: When you press the switch, listen carefully for any sound coming from the door. If you hear the motor running a slight buzzing o r whirring noise, but the window doesn’t move, it’s likely a mechanical issue with the regulator o r window tracks.
What to Look For: If you don’t hear the motor at all, then the motor could be dead, o r there might be a wiring issue preventing it from receiving power.

3. Check for Power to the Motor:

Method: If you have access to the window motor, use a multimeter to check if power is reaching the motor when you press the switch.
What to Look For: If there’s no power to the motor when the switch is pressed, the issue could be with the switch, wiring, o r a relay.

4. Inspect the Wiring and Connectors:

Method: Inspect the wiring to the motor for any visible damage, loose connections, o r broken wires. A broken wire o r loose connection could prevent the motor from receiving power.
What to Look For: Look for any frayed o r disconnected wires, especially where the door wiring bends when opening and closing the door.

5. Try the Manual Window Lift:

Method: Some cars allow you to manually raise o r lower the window if the motor is stuck. You can try gently lifting the window while someone presses the switch.
What to Look For: If the window moves manually, but the motor doesn’t seem to work, then it’s likely the motor o r regulator is at fault.

6. Inspect the Regulator:

Method: If the motor works but the window doesn’t move, the issue might be with the window regulator. The regulator could be broken o r out of alignment.
What to Look For: Listen for strange noises from the motor o r feel for resistance when operating the switch. A faulty regulator may need replacement.
