What are the reasons for the malfunction of the Mazda6 power window?

There are many reasons for the malfunction of the Mazda6 power window. A detailed analysis is as follows: 1. Aging of the window seal: The window seal (including the inner trim) may age, become dirty, or deform, which can create resistance when the window is raised or lowered. 2. Dirty guide rails: The window guide rails may be too dirty. This is also a lubrication issue—cleaning the guide rails and applying grease can resolve the problem. 3. Motor failure: If the window is difficult to raise or lower despite sufficient power and no resistance, the motor may be faulty. 4. Window regulator failure: This includes issues with the guide rails, cables, or sliders. 5. Improper window seal: Some vehicles may have improperly fitted window seals.
I once had trouble with my power windows malfunctioning. It happened after a car wash when I accidentally pressed the switch but got no response. I tried checking the fuses myself and found the window fuse in the fuse box had blown, probably due to short-circuiting from water vapor during the wash. After replacing it with a new fuse, everything worked normally again. I also learned to maintain window seals during rainy seasons to prevent water ingress. Such issues are more common in humid seasons, and delayed repairs can damage other components. I believe regular electrical system checks can prevent many minor issues—safety first, after all, as being unable to drive is frustrating. Since then, I test the fuses every few months. It's also good to keep spare fuses in the car just in case. Overall, checking simple components first before seeking repairs saves both money and hassle.
My Mazda6 is 10 years old, and the power windows sometimes malfunction, especially making strange noises in winter. Last time I took it for inspection, the mechanic said the window regulator was either rusted or had dust stuck in the tracks, affecting mechanical operation. After cleaning the dust and applying lubricant, it worked fine again. Possible causes include dry tracks, aging motors, or long-term parking in dusty areas accumulating grime. I now clean the tracks monthly to reduce friction, and haven’t had major issues since. If the windows move slowly or make noise, it’s a sign they need maintenance. I recommend using silicone-based spray to lubricate the tracks instead of regular grease to avoid attracting dust. Park in cleaner spots for easier upkeep. If the window gets completely stuck, you’ll need to replace the entire regulator assembly, which is costly and labor-intensive. Paying attention to early symptoms can save a lot of trouble.
