Wiring and switches

The process of converting manual windows to electric ones involves several steps, including wiring and switch installation. Here is a detailed guide to help you through the process:

Firstly, you will need to source the necessary parts. This includes purchasing a power window conversion kit, which typically includes switches, wiring, and hardware. You can find these kits online or at specialty automotive stores. It is also recommended to have basic tools on hand, such as screwdrivers, wire strippers, electrical tape, and connectors.

Before beginning the installation, it is crucial to review the service manual specific to your vehicle. This will provide important information on the disassembly process, as well as the location of various components. Additionally, you should refer to an electrical schematic of your vehicle, which can be found in the owner's manual or online. This schematic will guide you in tracing the wiring from the fuse panel to the switch, ensuring there are no breaks in the connection.

Now, let's discuss the wiring process. You will need to begin by removing the door panel, which typically involves removing screws and using a prying tool to pop out the clips around the perimeter. Be cautious, as you may need to remove additional components like weather-stripping or door moldings. Once the door panel is removed, carefully set it aside, as you will need to reinstall it later.

With the door panel removed, you can access the window mounting bolts. Loosen and remove these bolts, and gently set aside any protective plastic door covers. Now, you are ready to install the new power window regulator. Line up the regulator with the window and use nuts to hold it in place temporarily. Have an assistant slowly lower the window until the brackets align, then secure the regulator with bolts.

The next step is to connect the wiring. You will need to disconnect the existing wiring by removing the clips and grommets using pliers or a wrench. Be cautious not to use sharp tools that could damage the components. Once the old wiring is removed, connect the new wiring from the motor to the power source and switches. Ensure that the connections fit together securely.

Finally, install the new window switch by plugging the connectors into the switch and snapping it into the door panel. Test the window to ensure it operates smoothly and that the switches function correctly.

Converting manual windows to electric ones can be a complex process, and it is important to be prepared and follow the specific instructions for your vehicle.

Removing the trim panel

Before starting, ensure you have gathered all the necessary tools, including a Phillips screwdriver, a flathead screwdriver, wire strippers, electrical tape, butt connectors, power wire, wrenches, sockets, grease, a multimeter, a small battery, and more. Having these tools ready will make the process smoother and prevent any delays.

Now, let's begin with the removal process:

  • Locate the trim panel: The trim panel is the decorative covering around your window, usually made of plastic or vinyl. It may have a simple design or include additional features such as window controls or storage compartments.
  • Remove any screws or fasteners: Carefully examine the trim panel and identify all the screws or fasteners that hold it in place. Use the appropriate screwdriver or tool to remove these screws. Place them safely aside, as you will need them again during the reassembly process.
  • Gently pry the trim panel: Using a flathead screwdriver or a similar tool, gently pry the trim panel away from the door frame. Be careful not to use excessive force, as you don't want to damage the trim panel or the surrounding areas. Start from one corner and slowly work your way around the panel.
  • Disconnect electrical connectors (if applicable): If your trim panel houses window controls or other electrical components, carefully disconnect the electrical connectors. This step may vary depending on your vehicle's make and model, so refer to your car's manual or seek guidance from online resources specific to your vehicle.
  • Set the trim panel aside: Once all the screws and fasteners have been removed, and any electrical connections disconnected, carefully set the trim panel aside. Place it in a safe area where it won't be damaged during the conversion process.
  • Be cautious of sharp edges: When handling the exposed door frame and components, be cautious of any sharp edges or protruding parts. Wear gloves, if necessary, to protect your hands.

By following these steps, you will successfully remove the trim panel, providing access to the inner workings of the window mechanism. Remember to take your time and work carefully to avoid any damage to the trim panel, door frame, or other components.

Installing the window

Installing electric windows is a complex process that requires a lot of tools and parts. It is recommended to have a spare set of hands to help with the installation.

First, you will need to remove the door speaker panel, door armrest, and inside door handle. Be careful when removing the door panel as the upper door trim piece is often brittle and ready to come apart. Start with the lower bottom panel and work your way up towards the upper door trim panel.

Next, you will need to position the window to access the screws that hold the glass to the bracket/slider track. Once you have removed these screws, take out the window stoppers. Now, carefully pull the glass up and at an angle to remove it.

At this point, you can install the electric window motor and bracket. You will also need to attach the cables to the manual regulator. If you are installing on the driver's side, you may need to remove the window cranks.

Finally, hook up the wiring. The ground wire should be hooked up to a ground screw, the 12v wire to a dedicated wire with a fuse holder to the battery, and the relay signal to something that turns on with the key, like the radio.
