Problem overview

Some Ford Mustang Convertible owners report experiencing rear window glass detachment from the top, which can lead to potential water leaks. This known issue often results in the glass becoming completely loose from the outer layer of the convertible top while the inner layer remains sealed, creating gaps for water to enter. Repairing this detachment typically requires specific tools and materials, such as suction clamps and adhesives, although some owners have successfully reattached the glass themselves using proper techniques. It is crucial for owners to ensure that the rear window assembly, including the glass, motor, and frame, is securely fastened to prevent pivoting and the formation of gaps. Additionally, adjusting the alignment of the rear windows to ensure they flush properly with the front windows can help mitigate detachment issues. Checking for loose bolts is also essential to avoid further complications. For those needing a more permanent solution, replacement options for the convertible top, with or without the glass, are available at varying costs.
