GMC Yukon Window Regulator

Finding Out Why Your Gmc Yukon Window Regulator Failed

The window in your vehicle is composed of various parts that allow it to function smoothly. Among these components is the window regulator, which specifically controls the movement of the window. If it gets damaged, expect the window to start malfunctioning as well. Usually, a damaged window regulator causes the window to get stuck or to be completely incapable of moving up or down. When this kind of trouble happens, try the following methods to confirm if your Gmc Yukon window regulator is broken and causing these problems:

Window misalignment

This problem usually occurs as a result of wear due to excessive side-to-side movement or constant friciton in the window frame. The bolts or bushings become loose, causing the regulator to be worn. A mechanical crackling noise can be heard as well when the window is being opened or closed. This sound is a common indicator that the window regulator is about to reach its end.

You can opt to replace the unit to fix the problem, but realigning the window could still be possible. You need to remove the door panel so that working on it would be easier. Just be careful in removing the bolts that connect the window regulator to the window. Once the regulator and window are detached, properly align these two parts while making sure that the holes of the regulator are also aligned with those on the window. Secure them in place using the bolts that you've removed earlier.

Window stops working

When your window does not budge at all no matter how many times you turn on the switch, a visual inspection would have to be done. Look closely for a broken connection or a blown fuse. It's pretty easy to spot a damaged fuse. Just look through its transparent case and try to find a broken filament. If any of the two indicators are present, you need to replace the damaged component immediately. Remember that in this case, it is not necessary to change the whole window regulator unit. However, if there are no damage on the fuse or connection, checking the voltage would be helfpul. This would allow you to determine if there is current flowing in the system.

Also, you may check the joints of the window regulator for corrosion, breakage, or stiff movement. Any of these irregularities can cause the window to stop functioning. Replacing the window regulator would then be the best solution.

  • Keeping Your Gmc Yukon Window Regulator in Smooth Operation 27 February 2013

    You are able to protect yourself from harsh weather elements because you can close your car windows, and you are able to enjoy the wind and the heat of the sun because you can open them-all thanks to your fully functioning window regulator. However, it will not always be in good condition. Eventually, it will get into the point where it's totally worn out and can no longer be used. It can even wear prematurely especially if you're not keeping tabs with its condition. Know when it's starting to malfunction so you can avoid greater damage and inconvenience. Here's a routine you can follow to check how your Gmc Yukon window regulator is doing:


    Inspect the components of your window regulator.

    Usually, it's already too late when you find out that your window regulator is damaged. There are actually no signs that would warn you that it's about to fail. You just pretty much know that there's something wrong with it when you're already unable to move your window up and down. However, you can schedule a maintenance check regularly to make sure that it's still doing well or if some of its components already need to be repaired or replaced.


    Check the fuse.

    Check the fuse connected to your window regulator as well as the wire cables. Lubricate these cables using a WD40 spray with extender tube, which would work its way down to the cable mechanism of your regulator and keep it unfreezed. Also, look out for broken connections. If there seems to be a problem, get your voltmeter and check if there is enough electrical current flowing in the system.


    Replace the bushings.

    You may change the white bushings in your window regulator every two years to prevent it the grease from drying out. This usually results into too much friction and resistance, affecting the smooth operation of your regulator.


    Lube your window regulator.

    Make sure that you have cleaned your regulator before greasing it. Use an acid brush in applying grease on both the pie gear and the pinion gear. Put on some grease on the steel roller channels, too. Then, finish it off with 100% silicone spray.
