The most common problem with the 1999 to 2003 Mercury Cougar sunroof is the motion mechanism breaks away from the cable that pushes and pulls the sunroof open and closed. You can tell if this is the problem with your sunroof because the sunroof motor will whir, but the sunroof stays put, or moves a fraction. This is due to a design flaw, and cannot be fixed. The parts of the sunroof are either welded or riveted together, and do not come apart for service. In short, you have to buy a whole new sunroof. The part # is F8RZ63518A30AB for the sunroof. Google it to your own dismay. Did you check to see if there is a fuse for it? Try to locate an owners manual, they are usually marked what fuses are what or pull the cover off the fuse box(es) and sometimes they are written on the back of the cover what fuse is what. There may be several fuse boxes to locate, like under the dash by where you feet are, or out in the engine compartment.
