Electric Power Windows

Servicing an electrical system should be performed by a certified automotive professional only!

Always wear protective safety goggles and gloves before work begins.

For those of us who have owned vehicles with manual windows and have had to draped over the passenger side trying to roll down the window to talk to a friend as you leave from the curb, power windows are a blessing. But when electric windows stop working were do you look? The window is controlled by four main parts; the window motor, the window regulator, the part that holds the window and the control switch. When you move the switch one way or the other, an electrical current is sent to the window motor forcing the window to go up or down depending on the direction of the switch. Most window control systems are powered by a thermo fuse. A thermo fuse will cut power to the window circuit if to much electrical draw is being used. This serves as a safety device and helps keep the wiring from overloading do to over usage. (READ COMPLETELY BEFORE STARTING!)
