Re: roof question???
Well first off close the top and latch it completely, and see if you get the same thing, can your hear the pump working? if it does, does it sound like its running fast like empty of fluid? have you noticed any dripping fluids from either side of the car around the rear for a leaking system, the fluid will run out drain holes, hopefully you did not damage the top stack by driving it and possibly bending it out of shape or through the parameters off. Look in the service manual for top operation and how to check your fluid level and start from there.
