It happens to every car eventually. The water starts dripping in when it rains and there's a lot of wind noise while you drive; your car's weatherstripping has started to go bad. While there are probably a lot of other worse things that could happen to your car, having rain water leak into the interior is probably one of the most uncomfortable. You'll have water on your seats, in your trunk, and on the floorboards that could lead to fungi and bacterial growth or at least a big mess. The good news is that replacing your car's weatherstripping isn't difficult or expensive and it's something that you can do for yourself, although that's also something that a car repair specialist can do for you if you don't have the time.
The tricky part about fixing a problem with your car's weatherstripping is finding the problem spots. You might think that finding a leak would be easy when water's dripping into your car, but water can easily spread throughout a car without any indication of where the leak is. The wind noise that you hear while driving is actually a better indicator. Pay attention to where the noise is coming from while driving to help narrow down your search. Inspect the seals around the doorframe by squeezing with your fingers. Healthy weatherstripping is supposed to be pliable and should spring back when you squeeze. You should also pay attention to any cracks or holes. If you still can't find the leak, you can run a hose over your car and pinpoint the source of the water.
After you've identified the problem spots in your car's weatherstripping, the next step is to choose factory-replacement weatherstripping or generic. Those of us who are more frugal might fix the weatherstripping by bringing out the silicone sealant and duct tape but that's not recommended. We recommend going for the factory-replacement variety but generic is also fine as long as you make sure that you compare the new and old weatherstripping to make sure that the appropriate cross-sections, holes, and joints are all in the right places.
When replacing the weatherstripping, take out any screws and set them aside. Peel away the stripping along with its adhesive layer. Then you can wipe the area with a gentle cleanser and then dry the area with a towel. You can then apply weatherstripping adhesive and install the weatherstripping lightly. After making sure that everything is in the right place, you can press on the stripping more firmly. Replace the screws and allow the stripping to dry as directed.
Replacing your weatherstripping can also be done by your car repair Rock Hill SC specialist or a nearby recommended auto repair shop. By making sure that your car's weatherstripping is in tip-top condition, you'll save yourself from any whistles or wetness in the future.
