I cannot get my convertible top to go down.

There is a switch that is mounted on the frame of the convertible top on the left side near the rear passenger side headrest. If you bump, jiggle or wiggle this area it will then operate the top. There was a service bulletin that says to remove the switch and oval out the holes to correct the issue. I personally just bump mine when it acts up.
