Does anyone know how this set up works? where is the switch that detects that the boot is shut? A few times lately my boot is closed but the dash indicator is lit saying 'door open', its always the boot. Trouble is I've had an intermittant start problem and I think its linked to this as if the last thing I do is shut the boot and lock up sometimes the boot interior light must be staying on causing a drain. Suppose I could just take the bulb out but that would'nt stop the dash indicator coming on to say 'door open' so i would prefer to fix this. Anybody know how to adjust this set up?
