If your car has a squeaky window, there are a few things you can do to fix it. The first is to try to fix the window by using a plunger or vacuum cleaner to suck out the dirt and dust that is causing the window to squeak. If that doesn’t work, you can try using a hair dryer on high heat to heat up the glass and make it more flexible. Finally, you can try using a sealant or paint to fix the window.
