How to fit a window regulator

Today, many people own an car and enjoy the freedom it can provide. Unfortunately, along with the great opportunities that come with owning a vehicle there will be maintenance and repairs that need to be completed to keep the vehicle in operation. A window regulator is one of those parts that can wear out with use or even break in an accident. There are many reasons one could need to be repaired or replaced and this guide will give information on the process.

The goal of this guide is to provide the information about what a power window regulator is, how to assess a problem with one, where to obtain a replacement. It is important that everyone research and gather all the information they can before starting any repairs. This will help people be confident when working and prevent mistakes.

Power Window Regulator Defined

With most vehicles today, the majority of operations are automated and run by electricity. The up and down motions of the windows fell into this category with the invention of the power window regulator. Window regulators were common in an automobile by the 1960s, but most were run manually by a hand crank located on the inside of the door. During this decade, the power window regulator was invented and gained popularity quickly.

The regulator is the same basic design with the difference being a small electric motor now attached instead of using a hand crank. The regulator is made up of a "c" channel that the window sits in and a scissor-pulley system attached. The motor or crank is attached to one side of the "scissor" arms and causes the "c" channel to move up or down. If the window is not moving, there can be a few reasons why that is and there are some ways to assess the problem.

Fixing a Power Window Regulator

To fix a power window regulator, it is important to not only understand what it is and how it works, but to see the parts in motion, so it is possible to properly assess the malfunction. The following steps will help readers work through how to discover the problem with their vehicles and how to fix them.

Assessing the Problem

The two main reasons for the power window failing in a car are the regulator itself is in need of replacement or the electric motor is faulty. An easy way to discover the problem is to try to move the window using the controls located on the inside door panel. If the button is pushed and there is a humming sound like the motor is running, but the window is not moving, then the problem is most likely with the regulator. If the button is pushed and there is no sound coming from the motor, then there might be a problem with power reaching the motor or the motor might be in need of replacing.

It is best to check the fuses and verify that they are functioning and power is reaching the motor before dismantling the vehicle door.

Accessing the Window Components

To diagnose the malfunction properly, the inside door panel needs to be removed so the window components are visible. Different makes and models of vehicles will have a variety of ways that the door panels are secured and it is important to research the specifics of each automobile before dismantling any parts. Places to find specific vehicle information are the manual,, online, and in automotive repair books..

Most door panels can be removed with a screwdriver or wrench. Make sure to first remove any pieces that are holding the panel in place, like the door handle or arm rest. There should be screw heads visible, but some vehicles have small plastic covers to hide the screws. Using a flat tip screwdriver, pop off the covers and then use the appropriate tool to remove the screws. Then, disconnect any wiring or cables running to the window controls or door locks. Once these pieces are off, slide the door panel up and out, but make sure to check resources before doing so to verify there is no other hardware in place, to avoid damaging the door.

Deciding What to Repair or Replace

Once the door panel is off, the first thing to do is verify the wiring from the motor and to the control panel are functioning. Check for signs of wear or disconnection before removing any other parts.

If the wiring is in order and the troubleshooting steps have been completed, the next step is to remove the regulator or motor. Look at how the items are attached to the door and make sure the door will not be damaged if they are removed.

Some door designs are made with the motors or regulators as permanent parts, and if so, this is when it must be brought to a professional to see what can be done. There are many other door designs where the parts are easy to remove and it may take only a few tools, such as ascrewdriver,, ratchet,, or Allen wrench.. If removing the parts at home, be sure to retain all hardware in case it’s not included with the new parts.

Final Result

Some vehicle repairs can be simple and it gives many owners the opportunity to fix the problems themselves. This can mean more knowledge for owners and less cost to fix issues.

Unfortunately, not all vehicle designs give owners the option to perform certain repairs themselves. Therefore, some readers will find they have to bring their car to a professional and have the problem taken care of, but it is important to be knowledgeable about the types of malfunctions and ways they are repaired. This will help people be confident that their vehicles are being repaired properly and protect them from poor service professionals.
