does anybody know where the siren is fitted on a 02 c5, my father is selling his c5 so i've got the alarm, i fitted it to my car and turned it on with the lexia, all seems fine but there is no sound.
i took out the alarm box from behind the fuse box and the ultrasonic sensors that were connected into it,
i fitted them into my car, then installed them with the lexia, a scan revealed no faults but when i go into the actuator tests i hear no sound when i select the siren.
