Maybe another car backed up into your car door, or maybe a wild shopping cart came flying at it, but whatever the cause, there's a dent in your door. It may seem like it's nothing but a minor eyesore, until you try to roll down your car window and it suddenly stops, stuck partway down: try as you might, it won't go any further. If you've found yourself in this unfortunate situation, this guide can help you to troubleshoot the problem and attempt to fix it.
Why The Window Won't Roll Down
Car doors are made of three layers: the internal layer that your armrest and controls are affixed to, the window channel that holds your glass window, and the exterior frame, which is now dented. Unfortunately, when a dent is large enough or deep enough, it can press far enough inwards so it blocks the path of the window when it tries to slide down. If this space becomes pinched, automatic windows won't go down any further once the glass reaches the pinch, and manual car windows can't be forced any further without risking damage to the glass.
If your car door is so severely dented that the damage visibly extends to the interior of the door, you'll need to go to an auto body shop. However, if there's no visible damage on the inside of the car, you may be able to fix the window's functionality by repairing the dent.
Removing the Dent
Small to medium-sized dents can be removed with one simple tool you probably already own: a standard plunger. When removing dents from cars, avoid plungers that have accordion-like bodies that are designed to produce extra force and suction on toilets. These plungers might create too much suction and damage the paint job of your car.
To remove the dent, take a clean, dry plunger and align it over the dent so that it covers the entire dent. Slowly lean on the plunger so that it's pressed in entirely over the dent, like you're pushing down to plunge a toilet. Then, gradually and slowly pull back on the plunger: again, don't yank, as this can create too much suction or uneven suction that could damage the paint job. Try to pull back in one slow, smooth motion. If successful, your dent should be completely repaired or the dent will be reduced in size. If it's reduced but not completely removed, repeat the step until it looks perfect.
Now, try to roll down your window. If the dent was fully pulled back out of the window's path, the window should now be able to go down smoothly. If it still won't roll down, that means there's permanent damage to the inside of the external frame, and you'll need to take the car to an auto body shop, like Superior Paint & Body Service Ltd, to have the channel repaired or replaced.
Car dents can be a big nuisance, especially when they affect the functionality of car windows. Thankfully, repairing minor to moderate dents doesn't require special equipment or a lot of money, so give these tips a try.
