How to stop my car window from sliding down?
You can stop your car window from sliding down by taping the glass with the window frame. You can use duct tape to fix the glass with the frame on both sides.
Vice grips can also be used to wedge the window from sliding down. The advantage of using vice grips is that you can easily hold the window up or pull it down as and when required.
Why does my car window keep falling down?
A car window may keep falling because it is dislodged or stuck down. A broken control arm, a short window motor or a broken regulator can also cause the car window to keep falling down.
Some of the reasons why a car window keeps falling down are:
- Dislodged window
- Broken control arm
- Broken regulator
- Short window motor
Dislodged window
Over a period of time, the rivets connecting the regulator and the windowpane may break and/or wear out. The regulator will not be able to hold the window up and hence it will keep falling down. Getting a new regulator fitted will solve the problem.
Broken control arm
By the time the car gets old, the control arms of the window may be broken. To spot the issue of a broken control arm, you will need a mechanic to remove the door panel and help you with fixing a new one.
Broken regulator
In cars having power windows, there is a regulator that controls the sliding motion of the glass. When this regulator is broken, the window keeps falling. Replacing it with a new one will address the problem.
Short window motor
The power windows in a car are controlled using motors. When this motor shorts out, you won’t hear a click if you pull the switch up. This indicates the need to get a new motor fitted at the earliest.
Why does my electric car window keep falling down?
An electric car window may keep falling because of a failed window motor, a malfunctioning regulator or faulty switches.
- Failed window motors
- Malfunctioning window regulators
- Power switches
Failed motors
The motors that supply power to the switches may wear out and cause the power windows to fall down. Also, overheated motors can cause problems. Replacing the motor should help.
Malfunctioning regulators
Regulators control the switch that helps to slide the window up and down. With time, these regulators may become faulty and result in windows falling. Changing them will solve the problem.
Faulty switches
The switches start failing and lead to the car windows falling. These are the buttons that you pull up or push down to slide the window up and down. Replacing the switches will address the issue.
Lists of parts of a car window
| Name of the part | Description |
| Glass | The glass of the car window blocks the air and dust out of the car when pulled up. Also, this glass is capable of protecting the passengers in the car from the harmful ultraviolet rays of the sun. |
| Sunroof | The sunroof is provided in the cars to let more natural light into the car. Most sunroofs come tinted to prevent excess heating of the car cabin. |
| Sunroof Rail | The sunroof rail supports the sunroof of the car and holds it in position. |
| Sunroof Glass | The sunroof glass allows natural light to illuminate the interiors of the car. The glass is often tinted to let only a limited amount of light to enter inside the car. |
| Window Motor | The window motor supplies power to the window regulator to slide the window up or down as and when necessary. |
| Window Regulator | The window regulator allows the passengers of the car to slide the window up and down as per requirement. |
| Windshield | The windshield is an important element of the car windows as it pushes the airbags to open towards the passengers. This saves the car passengers from injuries in case of accidents. |
| Window Seal | The window seal blocks the slightest dust and rain from entering the car cabin. It’s usually made of rubber to provide airtight protection to the car. |
