The reasons why the Focus sunroof cannot be closed include: 1. Lack of regular maintenance by the owners. 2. Faulty sunroof wiring. 3. Damage to the sunroof drive motor. 4. Obstructions in the sunroof track. 5. Severe lack of lubrication in the sunroof sliding mechanism, causing the sunroof seal to stick to the car body. Below is some related information: The main maintenance for the sunroof involves lubricating the sliding tracks. If lubrication is insufficient, over time, it can lead to abnormal noises, poor movement, incomplete closure, or even jamming and misalignment, which may burn out the motor. Precautions for using the sunroof: 1. On bumpy roads, it is best not to fully open the sunroof to avoid excessive vibration between the sunroof and the tracks, which could deform related components or even damage the motor. 2. Before opening the sunroof, always open the sunshade first to prevent overloading the sunroof motor, which could lead to malfunctions over time. 3. In winter or after rain or snow, the sunroof may freeze, and the seals could harden. If the sunroof is opened immediately under these conditions, the rubber seals may crack. If the sunroof is frozen, the motor could be damaged due to overload. It is advisable to turn on the heater first and wait for the ice on the sunroof to melt before opening it. 4. When using a high-pressure water gun to wash the car, avoid directing the water stream directly at the seals. High-pressure water can deform the seals, leading to water leakage into the car, and may also damage the seals. 5. The four corners of the sunroof have drainage channels to direct water outside the car. If these channels are blocked by leaves or accumulated dust, or if the water volume exceeds the drainage capacity, water may overflow, causing roof leaks or even severe water ingress. Since the sunroof components are movable parts, they are more susceptible to water damage and aging. It is important to regularly clean the drainage outlets.
From a mechanical perspective, the inability to close the Focus sunroof is mostly due to track blockage or deformation. When I ran an auto repair shop, I frequently encountered this issue: the sunroof getting stuck while driving, often because small branches, dust, or bird droppings fell into the sliding track, blocking the path, or the track itself became deformed due to wear, causing movement to be less smooth. If the track is fine, it could be a motor malfunction, failure to transmit the switch signal, or a control module issue. A blown fuse is also a common cause, especially during electrical overloads. In such cases, first try manually cleaning the track, using a vacuum to remove debris or gently brushing with a soft brush. If that doesn’t work, check the fuse box to see if the sunroof fuse has blown. If the problem persists, seek professional inspection as soon as possible to prevent rainwater leakage from damaging the roof lining or causing electrical short circuits—safety first.
