My Alarm is being triggered after being sat for an hour or two,the alarm sounds for about 10 seconds then goes silent,when I return and turn on the ignition I'm given a 'ALARM TRIGGERED,R/H FRONT DOOR' message,I'm aware it's my drivers door but not sure where the micro switch is or why it's doing it,I suspect it's when I close the tail gate and the air pressure forces the door outwards,any ideas?thanks.
