Driving with a window seal leak can be particularly annoying for both the driver and passenger, and resealing a door can be expensive.

Instead, Clay, a professional mechanic who posts easy DIY car repair tips on TikTok (@theclayway), showed a simple and inexpensive way to fix the leak using a piece of wood.

An air washer is essentially an inflatable pry bar intended to be used as a wedge for window, door and closet installations.

“I’m going to show you a great trick that I guarantee will come in handy someday,” Clay said at the start of the video.

“Have you ever had a door that leaked and the noise was annoying as hell, like my voice?”

He then shows a piece of air escaping through the window seal, creating a sickening hissing sound into the cabin.

“Here we are driving down the road and all we can hear is the intrusion of air,” he said.

He then showed his viewers the inside of the door frame, where the weatherstripping is strategically placed to prevent air and water from entering.

Clay said it’s important to check and make sure all weatherstripping is in place because the trick won’t work if the weatherstripping is missing.

“Make sure [the weather stripping] “It’s all there,” he said.

He pointed out that it was all over the sides of the window and door.

Once he determines that everything is where it should be, he reaches for his tool of choice, a rubber mallet – although he recommends his viewers use something a little more organic.

“A piece of wood works really well, but I can’t seem to find one for some reason,” he said, placing the hammer in the middle of the door frame.

He then places his hand on the top corner of the door frame, where there is usually a leak.

“Press really hard here, almost like a rocking motion,” he said.

“It’s going to want to bounce back, so you have to push it a little further than you think it needs to, you just have to put some pressure on it.”

He assures his viewers that even though things may look bad, there is nothing to worry about.

“Don’t worry, you won’t break the stupid thing,” he said.

Once you have applied enough pressure, the door should sit flush against the vehicle frame, reinforcing the seal.

“Now when I open my door, I no longer have a large gap or air leaks. Nice!” said Clay.
