SOME OWNERS MAY COMMENT ON AN OBJECTIONABLE CLICKING NOISE HEARD WHEN CYCLING THE DOOR GLASS TO ITS FULL UP POSITION.
DUE TO PREMATURE WEAR OF THE PVC COATING ON THE UP-STOPS, THE GLASS WOULD TRAVEL UP AN ADDITIONAL 1 - 1.5MM (3/64 - 1/16 INCH), CAUSING THE GLASS TO CLOSE OUTSIDE THE BLOW-OUT CLIP. THE PVC COATING WAS DELETED FROM THE UP-STOP, ALLOWING METAL TO METAL CONTACT OF THE GLASS GUIDE BLOCKS HITTING THE UP-STOPS.
