Replacing a Faulty GMC Window Motor
- When a GMC window motor fails, there are often indicators of oncoming failure, such as windows working intermittently or malfunctioning permanently, windows failing to roll automatically, and windows moving at faster or slower speeds.
- To correctly diagnose a window motor failure, you have to test the motor using a voltmeter or a multimeter to see if there is power at the motor switch and at the connector.
- Search for a window motor replacement that is specific to the year and model of your GMC vehicle (take note that some window motors come as a separate unit, while others are integrated into the window regulator as an assembly).
- Per unit, a GMC window motor may cost around $20 to $170. For a set of two, expect to pay around $40 to $120, while a set of four typically costs $100 or more.
GMC’s line of pick-up trucks, SUVs, and vans is marketed as a cut above the average vehicles. They usually have more brawns to flex and more luxury features to brag about. Like any late-model vehicle, they are equipped with many convenient features, which includes a power window system. A GMC owner normally would not think much about power windows until their windows get stuck or fail to work. In which case, a bad window motor is often blamed.
When to replace your GMC window motor
When your GMC window motor and GMC window regulator fail, they do not usually happen out of the blue—there are often indicators of oncoming failure. Here are some of the signs of motor problems that have been reported by some GMC owners:
Window works intermittently
When the window ceases to work temporarily, this can be the effect of an overheated motor. Once this window motor cools down, it will be able to operate again and supply power.
Window no longer works
Since the power windows system runs on electronics and the motor is the one supplying power, window failures are usually linked to a malfunctioning motor.
Window does not automatically roll up or down
As soon as you press the button, the window should start sliding up or down. If it takes more than a few tries, then this is a good indication of a faulty regulator-motor assembly.
Window moves slower or faster than usual
If the window is working but seems to be struggling, this may be caused by an underperforming motor. When the window moves faster than usual, this is often attributed to an electrical trouble with the regulator-motor assembly since the window system is supposed to run at a set speed.
Testing the motor
When your GMC power windows fail, a bad motor is not the only thing to blame. They may also be caused by a blown fuse, a broken switch, a faulty regulator, a stripped wiring or gear, or a combination of these. To correctly diagnose a 2014 GMC Terrain power window motor problem or any GMC window failure, you have to check the motor using a voltmeter or a multimeter. With this, you can tell if the GMC window motor is not receiving voltage from the battery. A service manual for your GMC will guide you in running the test to detect power at the motor switch and at the connector.
How to find the right GMC window motor replacement?
Here are some of the things you have to consider before buying a window motor replacement for your GMC vehicle:
Search for motor replacements that are specific to the year and model of your GMC (although the window motor used by your vehicle may be the same for other GMC models and GM vehicles). Take note that some window motors come as a separate unit, while others are integrated into the window regulator as an assembly. With a compatible replacement, installation will be as straightforward as plug-and-play.
Check the condition of GMC window motor replacements—not all of them are sold as brand-new. Some of them are remanufactured, which means that they have been stripped to replace worn-out components. Remanufactured motors are designed to work like a brand-new unit; some even claim that they have been enhanced with more durable gears. Remanufactured parts are more ecological since less raw materials and less energy are used in building the part.
Take time to read the product details, especially if you are buying a remanufactured part or if you are choosing from a wider selection of replacements from aftermarket manufacturers. See to it that the motor is tested for speed and strength. In case of a remanufactured part, make sure that the magnets are recharged and that the part is lubricated.
Per unit, a GMC window motor may cost around $20 to $170. For a set of two, expect to pay around $40 to $120, while a set of four typically costs $100 or more. These prices are just estimates and may change from time to time.
