Hi all, sorry if this has been solved somewhere, but I have spent a while searching and not found anything.

When I lock my (SE Roadster) car, the indicators (blinkers?) flash, the car locks and the red light on the tow away alarm switch starts to flash. However, if I reach inside and open the door (with window down or top open) no alarm sounds.

Any ideas where I should start to fault find? I am guessing that maybe the siren is disconnected? Where is the siren located on the Crossfire?

Thanks.
