Troubleshooting the Weatherstrips on Your Buick LeSabre

You've probably taken it for granted that you can drive your Buick LeSabre in all kinds of weather. After all, you can stay comfortably dry inside your cabin whether you're driving on a sunny winter's day or during a refreshing spring shower. This is thanks to a set of seals that go around various parts of your car called weatherstrips. You can easily see these rubber-skinned strips along the inside of your doors where they also serve to make the car interior less noisy thanks to their soft sponge interior. Despite these important functions, your Buick LeSabre weatherstrips are not immune to problems. Here are a few ways in which you can find out what's wrong with them:

Hearing high-pitched whining inside your LeSabre

Weatherstrips can't last throughout the entire lifetime of your vehicle. Even if you didn't buy a used LeSabre, you might start hearing an annoying high-pitched sound inside your cabin whenever you drive. The sound is caused by wind that goes past your door seals. If you let it get worse, the wind will eventually get into the car and moisture will follow. But you'll be glad to know that if this leak is minor enough, you can plug it with an adhesive or a sealant.

Seeing cracks on the weatherstrip

If you notice that the weatherstrips around your doors, windows, and trunk are looking worse for the wear then you'll need to start looking for suitable replacements. Old, dried, and cracked weatherstrips have come to the end of their lifetime thanks to their constant exposure to the elements. The longer they stay on your LeSabre, the more likely it is to have your car and belongings affected by rust or mildew caused by moisture. You can do the job yourself or you could ask a body shop to install the new strips for you, especially if you've got one of the older LeSabre models. The good news is that many experts consider aftermarket replacements much better than the original equipment.

Closing doors and having them spring back

Sometimes, after you install new weatherstrips onto your LeSabre's doors, you might find that your doors can bounce afterwards, causing them to latch improperly. This is because the new seals are more vibrant than the old ones. You don't need to fret if this happens, just move the catch on the doorjamb further out so that the latch can catch once again.

  • How to Keep Your Buick LeSabre Weatherstrips in Shape

    Whatever the weather, you know you can rely on your Buick LeSabre to keep you comfortable during the winter, spring, summer, or fall. This is because your car has weatherstrips that block the elements from getting inside the cabin even if you're driving at high speeds. Made out of a sponge interior and covered with rubber, these strips have been engineered for other functions as well. They can keep corrosive moisture away from the mechanisms inside your door panels, cushion the connection between the door and the body panel, and make the cabin quieter. However, this wonderworker isn't immune from damages, so you'll need to maintain it regularly to keep it at its best. Here are some ways in which you can keep your Buick LeSabre weatherstrips in tip-top shape:


    Use grease on your weatherstrips

    To ensure that your weatherstrips continue to work for as long time, you will need to use a special grease or a silicone spray on your seals. Once a year, you'll need to wipe your strips clean. Afterwards, you'll need to apply a thin layer of grease with your fingers on all your weatherstrips. This will give them greater protection against the sun, which can dry out your strips and cause them to crack.


    Use a weatherstrip remover

    You might find it hard to remove a tattered old weatherstrip before you install an aftermarket replacement. To ensure that your LeSabre's paint isn't damaged and that your new seals fit perfectly, spray a weatherstrip-removing product around the area instead of just scraping the old bits off. Wait until the adhesive softens before continuing with your replacement.


    Use a good quality adhesive or a sealant

    If your weatherstrip is still in pretty good condition but it is letting air or water inside your cabin because of a small leak, you can try to remedy it with a weatherstripping adhesive. Make sure it's of good quality and that its color matches the weatherstrip itself so that any mistakes aren't glaringly obvious. Apply a small amount underneath the loose portion and seat the seal in place so that it doesn't warp. Alternatively, you can use a clear silicone sealer that comes in a tube. Just apply a small amount around the leak ant let it dry.
