Need help from all the experts on this board. Got my wife an 06 roadster about a month ago. I've been reading through a lot of threads on the subject but hoping that this new information might help in getting more specific guidance. The siren as never beeped, chirped or made any sounds until yesterday when we were driving on the highway at 60 mph and it chirped twice then nothing for 30 seconds then 2 chirps then nothing for 30 then 2 chirps so I pulled over, turned the car off, started it and it started fine. Turned it off again and pressed lock on the fob and not only did it lock the doors but I got 2 chirps!!! Got home, locked the car but no more chirps, tried panic button, nothing. Now, 1 1/2 days later, the siren goes off by itself in the driveway. I turned it off by unlocking the doors which is the only way it would stop. Now I've locked the doors, didn't get a chirp and the siren hasn't gone off again and I hope it won't in the middle of the night so here are my questions.
1- I don't want my wife to have this problem while she's alone and driving so is removing the siren the best solution until I can fix the problem or does anybody have another solution/suggestion?
2- Will removing the siren cause other problems?
3- Given the above information, does that point in a particular direction as to what the problem (s) is/are?
4- Will replacing the siren with a new one most likely solve these problems?
Looking for your guidance on this as I'm really at a loss right now.
Thank you all so much.
PS After reading more threads on the subject, it seems some owners have had problems caused by the glovebox anti-theft sensor and I happened to lock the glovebox for the first time before these problems started so could that sensor be part of the problems I'm having with the siren?

 

You can remove it and or replace it. If you unplug it all will be well. It is located in the center, under the cowl in front of the windshield. There are also drains in there that need to be cleaned periodcly.

 

If you decide to replace the siren just do it by having the cowl off once, out with the old in with the new and clean the drains of which there are four when you do it.

 

Thanks for the replies guys. I ended up removing the siren because it was getting worse and worse and the wife needed the car and the siren was coming on randomly and often and again, it was after she opened that glovebox so while I was at it, I took a look at the glovebox light assembly and checked both connectors. The light was not working and not burnt out but after closer inspection, there was 8.5V coming out of the 2wire plug but nothing going to the light so the small blue switch box must be shot. That being said, the other connector (4wire) has nothing coming out and certainly nothing going in as it would get power from the blue switch box which again seems to be shot. I'm guessing that the theft-alarm sensor gets a power indication when the glovebox is opened and the switch box is tripped but I'll have to figure that out later.

 

Didn't have time to do everything today but did take a look at the drain area and absolutely nothing in there except for a small leaf and a missing wiper nut cap and the drains I saw (only2?) were immaculate. Next time I'm in there, I'll look for the 4 drains you mentioned. Thanks.

 

One drain at each end and two in the middle.

 

The glove box light only works with the ignition on.
