On most cars the main power for all switches goesthrough the master switch located at the driver’s console. Sometimesthe switch is dirty causing the window to malfunction. If this is thecase, take the necessary steps to clean the contact and your problemshould be resolved.

2.Locate and remove the bolts holding the regulator to the door; it islikely you will have to manually lower the window in order to accessthe bolts.
3. Remove the old regulator, disconnect all wiring,and replace the old regulator with a new one you have purchased from aparts supplier. Shop online to find the best value as you will pay amint if you order one through a dealership.
4. Tighten the boltsholding the new regulator and reinstall the moisture barrier. Make sureall the wires are put back in the door before closing the door panel.
5. Engage the power window switch and the new regulator should work unimpeded.
