1. Power window motor and window regulator assembly installation procedure - CAUTION: Do not operate the power window motor until the glass installation is finished. Connect the power window motor to the body-side harness connector, and then turn on the ignition switch. Continue to pull the power window switch until the power window motor stops. NOTE: Power window motor stops automatically and the limit switch incorporated in the power motor will be reset. Turn off the ignition switch, and then remove window motor from the body-side harness connector. Align the power window motor drive shaft and the square hole in the drum by the following procedure, while using the guide and the opening in the motor housing as a reference for the installation position. Align the square hole with the drive shaft by sliding the glass bracket (glass mounting section) or by turning the drum using a ratchet wrench [with a socket diameter of 12.7 mm (0.50 inches)]. Turn the drum to position the glass bracket as shown in the illustration. Support the drum and the guide with your hand while turning the drum, otherwise the wires may pull out of the drum. If the wires pull out of the drum, re-insert them by following the drum and regulator wire installation procedure. Align the guide and the opening of the motor housing, and slide the guide into the motor housing while holding the guide and drum. CAUTION: Make sure that the metal cover is installed securely and does not move, in order to stop the drum from vibrating. If the drum vibrates, the glass may not slide up and down smoothly, or it may fall down. Install the metal cover securely to housing.
2. Drum and regulator wire installation procedure - Place the drum, guide and regulator on a work bench as shown in the illustration. Place the drum so that the square hole is facing upward. Place the guide so that the slits are facing upward. Place the regulator so that the glass bracket is facing downward. Position the glass bracket so that glass is in the fully-open position. Pass the springs over the wires, and then install the lowering wire to the guide first, followed by the lifting wire. (The lifting wire should be on top of the lowering wire.) Use some narrow-gauge wire [approximately 0.5 mm (0.02 inches) diameter] to compress the springs, and then tie the narrow-gauge wire to the slits in the guide. Insert the end of the lowering wire into the wire hole at the bottom of the drum, and then wrap the bottom so that there is no slackness in the wire. Install the lifting wire to the drum as following: Insert the end of the lifting wire into the wire hole at the top of the drum. Raise the front of the drum until the drum is vertical, and then position the lifting wire in the groove of the drum. Return the drum to its original position while holding the wires to make sure that they do not pull out. After installing the power window motor assembly to the window regulator assembly, cut and remove the wires witch are compressing the springs.
3. Operation check - CAUTION: Do not operate the window regulator assembly before installing the window glass, otherwise the limit switch will be set. Window glass safety mechanism does not operate when the window glass is closed fully at first time. Install the window glass to the window regulator assembly. Close the window glass completely. NOTE: Closing the window glass completely will finish the adjustment of the limit switch. Check that the limit switch operates correctly.
