Problem overview

Some Ford Mustang convertible owners report experiencing issues with their windows not closing completely, resulting in a gap after operating the top. This problem often occurs due to the gasket in the convertible top being very tight, which can hinder the electric lift motor's ability to achieve a full closure when the top is up. Additionally, some owners face challenges with the rear windows, requiring manual adjustments for proper alignment and cleanliness. The window motor is designed to sense when the door is closed and should fully close the window glass into the weatherstrip channel, a feature present in both coupe and convertible models. In some cases, manual override options may be necessary for the rear quarter windows when the convertible top is not fully up or down. It is advisable for owners to check the condition of the control rotors to ensure they are functioning properly, as this can help address alignment issues. Furthermore, lubricating mechanisms with WD40 Silicone Spray may resolve problems where windows get stuck near the top. If issues persist, further inspection of the window control system and potential motor problems may be needed.
