Power Rear-Window Wiring With the new power-window assembly installed, the electric motor and wiring harness need to be installed in order to provide power to the sliding window. Important: Included below are the steps in this automotive procedure as shown in the episode. These steps are general guidelines that are applicable to most vehicles. With any particular vehicle, there may be procedures, specifications, settings, tolerances, components, etc. that are specific to that vehicle. There are also variations according to the type of window kit you select. Always consult your vehicle's service manual when undertaking significant automotive repairs, and read and follow the manufacturer's directions and precautions that come with your kit or replacement parts. Safety Alert: Always wear eye protection, and follow proper safety precautions, when working with power tools. Safety Alert: As a standard safety precaution, always disconnect the vehicle's negative battery cable before you begin work on any electrical or mechanical components.
- The window-kit used in our demonstration was designed to fit the vehicle on which we installed it, so the motor mount lines up with existing holes on the vehicle cab (figure A). The kit comes with clips that install into the holes in the cab. Bolts are then used to secure the motor mount.
- With the motor-mount and motor secured according to the manufacturer's instructions, the next step is to attach the motor cables to the cab wall (figure B). Again, clips on the cable fit into existing holes in the cab -- along the rear wall (figure C) and behind the side panel.
- With the motor and cable installed, connect the wiring harness to the motor according to the manufacturer's instructions. The two ends of the wiring harness are visibly different (figure D).
One end connects to the motor, while the other connects to an existing factory-installed wiring harness behind the side panel. Consult the manufacturer's directions and your vehicle's service manual if you're unfamiliar with the existing wiring. Once the proper connection is made to the factory wiring, route the wiring harness (figure E) and replace the side panel.
- The next step is to install the dash-mounted switch (figure F). According to our manufacturer's instructions, the plug for this switch is located beneath the dash panel, near the headlight-switch assembly.
- Remove the panel and switch-assembly and locate the plug for the switch. To gain better access to the wiring, remove the small panel around the steering column (figure G).
- Next, remove the fuse-panel cover (figure H). Loosen and lower the parking-brake and hood-cable assemblies.
- Remove the bolts and clips that hold the lower dash-panel in place (figure I), and carefully remove the panel. Pull the panel out gently to avoid damaging either the panel, the clips or the wiring underneath.
- Unplug the existing switch (figure J) by pressing the release-tab at the top of the connector and gently pulling the plug apart.
- Our manufacturer's instructions indicated that an orange plug is the proper connection for the new wiring harness. We compared the connectors on the orange plug against the ones at the rear of the new switch for compatibility to ensure that we had located the proper connector (figure K).
- With the proper connector verified, the new switch can be plugged in (figure L). A locator tab on the switch ensures the proper orientation of the switch to the connector.
- With the switch and wiring harness connected, the operation of the power window can now be tested. Turn the ignition key to the ON position, and press the switch to check the operation of the new power window (figure M).
With a successful test, the final steps in the installation are mounting the switch on the dash and re-assembly. Those steps are covered in the segment that follows.
