How to Repair a Vinyl Window in a Convertible Top on a BMW

Updated February 21, 2017

Convertibles are popular because they provide the option of having the rooftop up or down depending on the weather. In many BMWs, the fabric convertible top has an immobile, vinyl window that provides another way for sunlight to enter the car. If the vinyl window should tear for any reason, you will need to repair it, and you can do the repair yourself with the right materials.

Use warm water and a mild detergent to clean the vinyl window. Soak the soft sponge with the soap and water, and then gently scrub the vinyl.

Cut off the jagged vinyl pieces surrounding the tear. Do not make the tear larger.

Use the measuring tape to determine the size of the tear, and then cut the patch down to size. Make sure it is at least 1 inch wider than the tear so you can apply enough adhesive.

Apply the adhesive to one side of the patch. Use a paintbrush for easy application.

Hold the patch over the tear, and then place it on the vinyl once in the right spot. Hold it down for a two to three minutes to ensure that it doesn't slip and dry in the wrong place. Allow 24 hours for the adhesive to dry and before moving the convertible top in any way.
