Mine finally gave up and broke. After 293k miles and a lot of open and close cycles, I am not surprised. The buffeting is like riding in a subwoofer enclosure unless I roll one of the windows down a bit and I'd like to find a NOS replacement unit, if the price isn't borderline insanity. Any sources? Otherwise, I suppose I could hit the local yards and try to find one that has some life left in it. I carry wood and pipe on my roof rack, so I would like to avoid one of the aftermarket units as I am confident that I would quickly find a way to break that
