1997 Lincoln Continental sunroof adjustments

Cycle moon roof from full open to full close position. Moon roof should be flush to 0.04" (1.0 mm) below roof at each front corner, and flush to 0.04" (1.0 mm) above roof at each rear corner. If adjustment is necessary, go to next step.
2) Remove shield retaining screws along front of opening. Slide opening shield and shade fully rearward to expose glass retaining screws. Loosen glass retaining screws, then tighten until they are snug.
3) If only front of glass is to be adjusted, loosen only front and center screws. If only rear of glass is to be adjusted, loosen only rear and center screws. Move glass upward or downward as necessary.
4) To check height, open glass about 4" (100 mm), then return it to closed position. Tighten screws to 9 INCH lbs. (1.0 N.M). To complete adjustment, reverse disassembly procedure
it may be seals that are old causing this as well.
