How do you reseal a factory sealed back window on a 1999 Chrysler Sebring convertible the bottom portion is no longer attached and it allows rain water into the car duct tape last about 2 weeks?

use heavy duty two sided 1 inch foam tape, bought at lowes but probably sells at auto parts store also. Just make sure its heavy duty, clean both surfaces and make sure they are dry. My repair is still holding after 2 years.
