Convertible BMW Window Installation Instructions

This repair will require 2 people (One person working from the inside, and one person working on the outside). Expect to spend at least an hour.

Repair should be done at temperatures at or above 68 Degrees F. Take off all jewelry (watches, rings).

Roll down all the side windows.

Lift Convertible top up about 6 Inches.

Starting in the Middle of the window on the outside, lift the piping with a butter knife and pull the fabric out of the profile, being careful not to damage the profile or your top.

Remove the rectangular shaped retaining clips (on the inside and outside of the window) by prying with a screwdriver.

Using a butter knife, or screwdriver unzip the zipper by prying between the 2 zipper ends. (you can also use an oversized zipper slider to unzip the window.) Once the zipper has been opened, it seperates easily, even without any tool.

Gently press the old window from the outside pushing in to remove the window.

Install the new window from the inside.

Using the provided zipper slider, zip in the new window. The factory install guide allows only 1 tooth offset to the right or left. I find it easier to start on the inside of the two zipper directions, so you are ending on the outside, but you can start the zipper slider in either direction.

Put the top back up all the way, but do not lock it.

Using a needle and thread, sew both ends of the zipper closed.

Apply the contact cement to the part of the window that will seal with the top and let it dry for 10 minutes.

Lift the edge piping of the window and insert the top material into the window.

If you are an international customer and want to save money on shipping the old window back to me, you can cut the old plastic off of the window, but please leave a full inch of visible plastic all around the zipper. Do not trim the plastic all the way back to the black zipper portion of the window.
