Eventually, rubber seals shrink, crack, and warp to the point they no longer properly function.
Window seals are a perfect example. In this article, we'll look at the top five ways you'll benefit from replacing weather-stripping seals around your vehicle's glass, including windshield, side, rear, vent, and quarter windows. We'll also discuss the most common types of automotive weather seals, and replacements we offer.
Water Leaks
While essential for life, water is an extremely pervasive liquid. During heavy rain or a carwash visit, water works its way into any gap or crack caused by warped, cracked, or crumbling weather-strips. We say water is extremely pervasive because it expands when frozen. So during countless wintertime freeze-thaw cycles, water expansion behind compromised weather seals only pushes them further out of shape. Plus, corrosion can easily form out of sight behind compromised seals.
With electronic control modules placed behind dashboards and underneath seats, modern vehicles can be significantly crippled by water leaks when it comes to operation and drivability. At the first sign of water entry, it's vital to have a leak diagnosed. Ruling out water drainage clogs, faulty weather-stripping is usually the cause.
Wind Noise
Ever notice how quiet any new car is at speed compared to an older vehicle? That's because all of the window and door seals are new and fresh -uncompromised by the ravages of time. Faulty weather-stripping cannot hold moveable windows in the exact alignment they were designed for. Water may not get through, but the whooshing sound of moving air does. And if you've got a noticeable whistle or related noise coming from window that's fixed in place, it needs to be addressed quickly before it becomes a water leak situation.
Sluggish Windows
Rubber weather-stripping must be flexible in order to allow moving window glass to slide by it easily. As sunlight and acid rain take their toll, weather-stripping along the inside and outside of window frames dries up and hardens. It may even become sticky as the rubber deteriorates. Smooth, effortless movement of window glass is replaced by sluggish operation because the large amount of friction.
Increased drag caused by weather-stripping friction also has a life-shortening effect on power window motors. So if your windows seem sluggish, check the weather-stripping first. There's a good chance new strips will solve the problem.
