Reconnect the window control switch panel. With the electrical connector disconnected, insert automotive test light (test light is grounded to body) into either side of the connector. Turn key to the on position (do not start the vehicle). Actuate the switch in both directions. The test light should light up in one direction. Repeat this operation for the remaining electrical terminal. Next, switch the test light lead to battery positive and repeat test. The test light should light in both directions but on opposite sides of the connector.

You must tape the window to prevent the window from moving. We use masking tape. This is used to keep the window in place while the window motor and regulator is removed. If tape or some other means of holding the window is not used, the window could slide down and cause damage or injury.
