When one of the power windows in your vehicle fails to function, it may be the result of a broken window regulator. If you have identified the motor as the issue, then replacing a power window motor is simple. We recommended that you review a service manual specific to the make and model of your vehicle when replacing the motor, as the methods used to disassemble car doors may vary from vehicle to vehicle.
The list of tools recommended to replace a power window regulator are as follows: Drilling tool and bits, painters tape, silicone spray, hex key magnetic, wrench, screwdriver, razor knife, white lithium grease, zip tie, magnet, plastic pry tool, socket wrench and sockets, gloves, and safety glasses.
We will review some general information before we get started on the installation directions. The first thing you will want to do is to ensure your working with a clean and dust free area. To begin, use silicone spray to clean the window run channels before installation. You’ll want to use a plastic pry tool rather than a screwdriver to remove the door panel to prevent damage. To avoid damage surface of residue, use painters tape to affix the window. Last, use a magnetic wrench and screwdriver to loosen or tighten the screws, nuts, and bolts.
There are essentially eight steps to replace a window regulator and motor assembly:
- Remove door trim
- Disconnect wiring
- Release connecting hardware
- Disconnect harness plug
- Install new window regulator
- Reconnect power supply
- Attach the window glass
- Test the window
Let’s go ahead and get started on the fitting. First, remove the interior door trim panel. Be sure to retain the hardware. Gently disconnect the wiring from the components inside the door. If a protective covering exists, remove it by hand when possible. Next, raise or lower the window glass to expose the hardware that connects the window regulator to the window glass. Then, release the connecting hardware, slide the glass up and affix the window in place. Next, disconnect the harness plug for the motor and release the screws to remove the window regulator assembly. Then, install the new window regulator assembly and secure the screws. Reconnect the power supply, raise or lower the window glass to expose the hardware. Attach the window glass in place with the hardware. And lastly, run the window up and down to verify the correct range of movement and operation.
