My 06 with convertible top is giving me an issue. Sometimes when the car would hit a bump in the road or go over an angled parking lot entrance, the widows goes down and the top alarm chimes. This used to only happen occasionally. Lately, it happens more frequent while driving down the road. I finally figured it out, it is related to the grab handle top release. If I twist the the grab handle and return it to the closed position the alarm goes off and the windows can then be closed. So, there must be a switch or sensor in the grab handle that is at fault. Anyone have any info on this and where to purchase it and how to replace it?
thank you
