to seal the sunroof? If the material is pliable, you might be able to get a grip on a strip of it and pull it out, one side at a time. I would not try to open the roof all the way at first. If there is a crank for it (mine has a removable crank for emergencies) turn gently after leaving car set in sun. As soon as you can see any of the exposed rails, squirt in a small amount of WD40 and close/open partially. As roof opens more, add WD40 to newly exposed rail surface working back and forth until you have it open. Once its open. inspect seals and repair/replace as required. If roof is electrically operated, fuse may be blown from an attempt to open it while sealed up.

Your best bet on radio is to remove and take/send to a shop familiar with brand/model of radio. Buying a rebuilt unit might be least expensive route.

Speedometer should be looked at by a shop which specializes in speedo repair. Look in yellow pages.

Dash lights could be blown fuse.

Clocks get gunked up and again replacement may be preferable to repair. Does clock light up at night? If not, may be associated with dash light problem.

Does anybody know if roof, if electric, shares fuse with any of the failing items?
