There is no reason to put up with a slow-moving or squeaky car window. Fixing it is easy. Just follow these steps:
Step 1: Clean
Wipe the body—door frame and area around the window seal—to remove any contaminants that could be causing friction and/or impeding the movement of your car window.
Step 2: Lubricate
Start with a dry moly lubricant—apply it to the seal on each side of the window frame. For best application, start at the top left side of the window and work your way down and then across the bottom. Your window should be open during the process so that the auto glass isn’t blocking your access to the seal. Also, be careful to apply the lubricant evenly over the vertical sides of the window frame.
Step 3: Work the Window
Once you’ve applied the lubricant, roll the window up and down a few times. This helps to more evenly spread or distribute the lubricant. With each subsequent roll-up/roll-down, the noise should get quieter.
Step 4: Repeat
If the window squeak persists, add the lubricant into the window’s seal when the window glass is rolled up, which may facilitate spreading the lubricant.
With some particularly stubborn windows, you might have to repeat the entire process…or bring your car to Astro Auto Glass for car window repair.
