Hopefully a simple question but should there be a lights left on buzzer when you turn off the ignition or open the door with the engine off and lights on? I feel like there was on mine but it no longer works (as proven by a flat battery recently due to lights left on!). But maybe I'm misremembering!
Ah my headlight buzzer must have stopped working then! Anyone else seen this/have any ideas for what might cause it to stop working? Related question - does the interior light come on only when you open the door or does it have a courtesy 'mode' and come on when you turn off the ignition/remove the key as I've seen in some cars? Wondering if that has also failed and it's no longer picking up the key being removed.
I was just looking at the warning buzzer wiring diagram. It shows that its power supply is protected by a 7.5A fuse labeled “FA Turn / Back.” You can download the service manual from this link: Service Manuals - 659cc model The schematic can be found in the 9899 folder, which contains several PDF files. The warning buzzer wiring diagram is located in the file named ED, under section D-93.
Thank you for that, the wiring guide was really helpful. As it turns out there are two buzzers on the car, one behind the instrument cluster (easily removed by pulling the trim around the dials out then unscrewing four screws). This one does the roof alarm (driving with roof unclipped). The lights on buzzer is just by the fuse box (small black box with white multi plug to it). This has an earth, an ignition live, another earth which goes to the door switches (earthed when closed) and two lives from the rear fog light switch and the lights switch. Test it easily by opening the door with the rear fog lights on and engine off. In the case of mine it must have been a dodgy connection as unclipping it, opening the casing and then reconnecting was enough to bring it back to life!
I didn’t realize there were two buzzers on the car. Luckily, it was an easy fix, and no more worries about drained battery. I should double-check mine as well. The schematic suggests there is also a buzzer for the room lamp. However, mine isn’t buzzing when the engine is off and the light is manually set to "On."
