I had problems with rear luggage light would not go out when door shut - alarm on dash flashed rear door open and then main alarm would sound when parked and locked - removed bulb but still exterior alarm sounded - removed rear tailgate panel and discovered rear wiper water hose was loose and water sprayed everywhere so reconnected hose - and gave electric fittings/locks a light spray with penetrating oil hoping this would fix light but no. So just disconnected wiring to lock switch - no more alarm but no light - any ideas ??
