What to Do When Car Windows Only Go Down but Not Up?
2 Answers
Car windows only going down but not up can be resolved by: 1. Ensuring all four doors are properly closed; 2. Using the switch to lower the window to the bottom and then raise it; 3. Holding the switch for 3 seconds when the window reaches the top and then releasing it; 4. Performing this operation for each door in the sequence of left front, right front, left rear, and right rear. The reasons why car windows only go down but not up include: 1. Damaged window lift motor or poor contact in the wiring harness; 2. Overheated components, causing the motor to enter a thermal protection state; 3. Blocked guide rails or aging rubber seals; 4. Loss of initialization data for the windows due to battery disconnection or maintenance work on other systems that disconnected the power or ground wire of the window control module; 5. Faulty window regulator switch.
I had the same issue with my car window last time—it would only go down but not up, which was quite annoying. First, check if the switch is stuck. Try pressing the window buttons repeatedly a few times, as sometimes poor contact can cause this. Then, listen for any buzzing sound from the motor inside the door panel. If you hear it, it means the motor is working but the regulator might be stuck or the tracks are rusty. In this case, you can try brute force—push the glass up manually while holding the up button. If that doesn’t work, it’s likely a blown fuse or a short circuit. Check the fuse box for the one corresponding to the window and replace it—it only costs a few bucks. If none of these solutions work, then the window motor is probably dead or there’s a fault in the switch assembly, and you’ll need to take it to a repair shop to remove the door panel. To reduce the chance of this happening, avoid letting kids play with the window switches too often.
