Power windows in cars should roll up and down freely and quietly with the flip of the switch in either direction. Some causes of clicking related to rolling the power window up and down can be repaired by the car owner. More complex problems require the attention of an automotive glass specialist and should not be attempted by the car owner in order to avoid damage to the electrical components of the power window mechanism.
Roll the power window completely down.
Spray some WD-40 along the inside track of the window. This helps to prevent the window from sticking and clicking in dry or humid weather.
Roll the window up and down twice. The window should roll freely without clicking and sticking.
Evaluate the source of the click each time you use the power window switches. If the click is coming from under the dash then replace the appropriate fuse in the fuse panel of the car. If the click is coming from the power door switch itself, take the car in to the shop for a repair. Replacing the switch is a complex issue that shouldn't be rectified by the auto owner.
