Packard introduced the first power windows in the 1940 Packard 180 series. This was a hydro-electric system. In 1941, the Ford Motor Company followed with the first power windows on the Lincoln Custom.
The "Hydro-Electric" system (windows, front seat adjustment and convertible top) was standard on 1947 model year. The full system was standard only on the high-end GM convertibles made by Oldsmobile, Buick, and Cadillac. It was only available as a package; that is, power assisted windows, front seat, and convertible top (where applicable). This feature can be identified in 1948 and later General Motors model numbers with an "X" at the end, such as the 1951 Cadillac Sixty Special sedan, model 6019X. Power assists originated in the need and desire to move convertible style tops up and down by some means other than human effort. The earliest power assists were vacuum-operated and were offered on Chy. Corporation vehicles, particularly the low-cost Plymouth convertibles in the late 1930s. The electrically operated hydraulic pump system was shared by Hudson and Packard for their 1948 through 1950 models. The seat and window assist system became available on GM closed cars (standard on some Cadillac Series 75 models and all Series 60 Specials, commonly called Fleet wood beginning with the 1948).The driver's door contained four buttons in addition to the remaining individual windows
Front driver-side windows malfunction most frequently because their motors and window regulators — which control the window's up and down movement — are used the most, mechanics say. But it can affect all windows and even power sun and moon roofs.
"We've been seeing this happen even on newer cars — cars that are 6 or 7 years old," says Robert Benet, general manager of Green & White Automotive in Spring, Texas.
Benet says it's important to take your car to an automotive professional as soon as possible. Malfunctioning windows can be a safety issue if people have access to your car through an open or partially open window.
"If it's down, you may not be able to bring it back up," Benet says. "And if it starts raining and you don't have a garage for your car , you could have a problem."
Window malfunctions are typically caused by a faulty window regulator (also called a window track), or a broken motor , cable pulley or window switch. Sometimes it can be a combination of those things.
One of the biggest reasons power windows fail is because of snow and ice, says Al Karam, owner of Classic Automotive Repair in Sterling Heights, Michigan.
"It freezes the door glass to the frame around the windows," Karam says. "The window regulators are not made to break ice free, and it prematurely wears out the window regulator mechanism."
Power window issues can be intermittent or permanent. Intermittent problems can cause windows to stop working temporarily only to work again and have more problems later. A permanent problem is when the windows fail to work again.
Overheated motors often cause intermittent problems, Benet says. When the motor - located inside the door - cools down, it may start working again. A technician will more than likely need to take off the door frame and check the motor and the wiring.
Benet says one of the biggest problems he sees is when the window regulator and cable come apart. The cable can break or come off the pulley.Type your paragraph here.
Window regulators are components that make it possible to lower and raise the window glass in a vehicle at will. In some cases, the regulator is manual, requiring aperson to operate the movement of the regulator using a hand crank. More commonly today,a window regulator is an automated device that is activated by pressing a toggle switch or abutton found on the arm rest of the car door closest to the window.With most vehicles, an automated window regulator system is configured so thedriver can control the movement of all windows in the car or truck. This effectively allowsdrivers to adjust front and back seat windows without using the controls situated by each of the passenger windows in the vehicle. Most makes and models continue to have individual controls situated near each window, allowing passengers to open or close the nearest window without calling on the driver to handle the task.Prior to the middle of the 20th century, a window regulator was usually operated using a hand crank. The cranks were situated at a convenient location along the door panel,making it easy for anyone seated near the window to simply grab the crank and turn itclockwise or counter-clockwise in order to open and close the window. Asthe hand crank was turned, a plate supporting the glass window would lower or raisethe window into the desired position. The construction of the crank made it possible to position the window so it was fully closed or open, or opened at a level that was to the liking
of the passenger or driver. By the 1960’s, the
power window regulator was gaining wide spread attention. Rather than operating the mechanism with a hand crank, this new innovation made it possible to open and close car windows be moving a switch or pressing a button on a control console. Originally, this feature was offered as an extra or luxury item on
many makes and models. However, by the end of the 1970’s, most ve
hicle manufacturersconsidered the inclusion of power windows to be a standard feature.Over time, the rear window regulator came into common usage. Along with thewindows situated near the seating area for the driver and passengers, the ability to raise andlower the rear window of an SUV, minivan, orstation wagonbecame desirable to consumers.This option was also considered a factory extra at one time but now is usually included as abasic feature of vehicles sold today.As with any type of mechanical component, a window regulator does sustain wearand tear after years of repeated usage. The origin of the problem with apower window regulator is usually based in the small motor that controls the movement of the window. When the motor begins to wear out, the regulator may not respond as efficientlyto the press of a button. Often, replacing the motor will restore full functionality.However, there are situations where the issue with the regulator is more complex thansimply a worn motor. When this is the case, replacement of the entire regulator may be necessary. Depending on the make and model of the vehicle, replacing an electric window regulator can be quite costly.
Power windows have come under some scrutiny after several fatal accidents in which children's necks have become trapped, leading to suffocation. Some designs place the switch in a location on a hand rest where it can be accidentally triggered by a child climbing to place his or her head out of the window. To prevent this, many vehicles feature a driver-controlled lockout switch, preventing rear-seat passengers (usually smaller children) from accidentally triggering the switches. This also prevents children from using them as toys and pets riding with their heads out windows from activating the power window switch.
Starting with the 2008 model year, U.S. government regulations required automakers to install power window controls that are less likely to be accidentally activated by children. However, the rules do not prevent all potential injuries to a hand, finger, or even a child's head, if someone deliberately holds the switch when the window is closing. In 2009, the U.S. auto safety administration tentatively decided against requiring all cars to have automatic reversing power windows if they sense an obstruction while closing.Proposed requirements concern "one-touch" up window systems, but most vehicles with this feature already have automatic-reversing. The federal government made a written contract that all automakers should make the lever switches (as opposed to the rocker and toggle switches) standard on all new vehicles by 1 October 2010.Type your paragraph here.
