The Toyota window regulator is what is mechanically responsible for moving your window up and down, whether it is powered by the power window motor or by your own efforts with a manually operated window. In addition to moving the window up and down, the Toyota window regulator helps to prevent the window from being pushed down when it shouldn't be, such as by someone wrongfully trying to get into the vehicle. If you've locked your keys in the vehicle before, you probably already know what a great job the Toyota window regulator does at keeping someone from entering by pushing the window down. It is the gears in the Toyota window regulator that produce that nifty effect, in addition to serving to move the mechanical plate up and down. The linkage in the Toyota window regulator holds the weight of the window as the mechanical plate move it. One step you may want to try before replacing a nonfunctioning Toyota window regulator is to spray it really well with a lubricant and let it soak in a while before trying the window again. If that doesn't work, then if you want the window to work, you'll have to go ahead and replace the Toyota window regulator. You can order your Toyota window regulator either online or via our toll-free telephone number, which is available 24 hours a day.
