What is the reason why the Mazda car window glass cannot be raised after being lowered?

Mazda car window glass cannot be raised after being lowered due to a malfunction in the window regulator switch. Here is the relevant information: 1. Type: The window regulator is the lifting device for car door and window glass, mainly divided into electric window regulators and manual window regulators. Nowadays, many car door and window glasses are generally lifted using button-operated electric lifting methods, employing electric window regulators. 2. The main reasons are as follows: The mud channel of the glass is deformed or damaged. The fixing screws of the regulator are loose. The window regulator is damaged. There is a deviation in the installation position of the guide rail. If all windows cannot be raised, it might be a circuit fault, and it is recommended to go to a professional repair shop for inspection.
My Mazda window had the same issue before—it wouldn’t go back up no matter what, leaving me scrambling. Generally, this problem could stem from a faulty window switch with poor contact (no response when pressing the button), a burnt-out motor (no sound from the motor), or wiring issues like poor contact or a short circuit blowing the fuse. Sometimes, dust buildup in the window tracks jams the glass, or the anti-pinch system mistakenly activates, blocking movement. I once checked the car’s fuse box—if the small fuse was blown, replacing it fixed the issue. For clogged tracks, cleaning dust with a fine needle and adding lubricant might help. If all else fails, don’t force it—head to a professional repair shop ASAP. Driving with the window down in summer (getting rained on or dust inside) is miserable. Get into the habit of regular window and door maintenance to avoid this hassle.
I often work on my car myself. When I see the window won't go up after being lowered, my first thought is that the internal contacts in the switch might be worn out and malfunctioning, so I repeatedly press it to test the response. If the motor is humming but not moving, the gears might be jammed. Alternatively, there could be a broken wire or a blown fuse, in which case I just need to check the fuse box and replace it with one of the correct amperage. It's quite common for debris to block the door tracks, so I use compressed air to clean them out and spray some WD-40 for lubrication, then gently push the glass manually to test. Insufficient voltage could also be the cause, so I check the battery. I recommend regular maintenance of the window lift system to avoid trouble, but for complex issues, it's more reliable to consult a technician.
