What to Do When Car Doors Won't Open in Winter?

[SanMadeline]

If car doors are frozen shut in winter, you can use a hairdryer set to low heat, directing it along the door seams for one cycle, then switch to high heat and repeat the process to thaw the doors. Immediately wipe away melted snow water with a dry cloth to prevent refreezing. Below are precautions for winter car use: 1. Low winter temperatures affect various vehicle components. Tires become harder as rubber stiffens, making them relatively brittle with reduced friction coefficients. Tire maintenance is crucial—consider switching to better winter tires. Monitor tire pressure, maintain tire sidewalls, and conduct regular inspections to ensure they remain intact. 2. To prevent door freezing in winter, inject a small amount of lubricating oil into door lock cylinders and apply a thin layer of grease around door seals to avoid freezing.
