The windows on a car keep the interior safe, warm and dry. They allow fresh air in and make it easy to order at a drive thru window. If a window gets stuck up or down it can create a very unpleasant situation for the driver and passengers.
There can be a number of different problems with vehicle windows. The issue can vary from a blown fuse to a window switch that is not working. In some cases the glass can actually fall into the door.
Regardless of the problem, it should be fixed quickly, a malfunctioning window is not only inconvenient, it can also be dangerous.
Power Windows
The glass sits in a part called a regulator, which is pushed up and down by a small electric motor. The motor is attached to a worm gear and a number of spur gears, which creates a gear reduction, producing enough torque to lift the window while also keeping it level. When the window button is pushed the door module closes a relay, which then provides power to the window motor. The majority of problems with a power window are caused by the electrical system but faulty gears can also be the culprit.
Manual Windows
The glass is attached to a regulator, which is the component that pushes the window up and down. The handle sticks through the door panel and when the handle is cranked it moves the regulator up or down. Manual windows are rapidly being replaced by power windows.
Blown Fuse: If none of the power windows are functioning there is a good chance that the problem is a blown fuse or a bad relay. While these are two separate issues, the symptoms are often very similar. A complete inspection of the fuses and electrical system will be necessary to determine where the problem is and how to repair it.
Burned Out Motor: if the windows are not going up or down and there is no noise coming from the door when the switch is pressed there is a good chance the electric motor is burned out or malfunctioning. The motor will have to be replaced.
Power Window Regulator: If the motor is running when the switch is pressed but the window does not move, the regulator is likely damaged or malfunctioning. There are a number of parts that can break on a regulator. In this situation the regulator will have to be repaired or replaced.
Malfunctioning Motor: If the window is still moving up and down but very slowly, the electric motor may be malfunctioning. If it is making a whining sound this can also indicate a problem. As the motor ages it will wear out and eventually it will have to be replaced.
Broken Window Tracks: There are window track guides, which hold the window in place as it goes up and down. If the track guides are damaged it can cause problems with the window going up and down. Common symptoms include a slow moving window, and a rattling or grinding noise. Eventually, the window may fall inside the door.
Worn Window Switch: The power window switch gets used a lot and eventually it can wear out which will prevent power from going to the window. If this happens the window can end up stuck in the up or down position.
Bad Wiring: Wiring is integral to the operation of the power windows and if there is a short, a faulty switch or a malfunctioning relay it can bring the whole system to a halt. A professional should deal with wiring issues.
Broken Regulator Manual Window: If the window is starting to tilt sideways, the most likely cause is a broken regulator. The wheels on the end of a regulator will often break off which will cause the glass to tilt sideways, and eventually fall into the door.
A top-rated mobile mechanic will come to your home or office to determine the source and cause of the window issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
A malfunctioning window is certainly not a life threatening situation but it can lead to interior damage and unsafe situations if the window is stuck in the down position. The flip side of that coin is a window stuck in the up position which can make it impossible to order at a drive-thru or use the window as an escape exit in the event of an emergency.
