Feb 11, 2009

-   87 covette. open door---horn,alarm goes off. has happened twice in last 5 years. unlock opposite door with key and alarm/horn is silenced. additionally, in SEVERE heat ,92 to 104 degrees, horn can blow spontaneously without provocation like the alarm has been activated. horn continues to blow until horn is disconnected,then reconnected when temperature falls below 80 degrees. Any thoughts?-   Guest
