battery dies every one to two days

[DGM]

Does anyone have instructions on how to replace the siren module or where to buy it?
Thank you!

You may have missed it but both concerns have been answered. See my two previous posts on this page.

Okay. I haven't found anyone to test the fuses with me. I'm not really know what most of this means and can't afford a tech. I disconnected fuse #38 for siren module and it seemed to do the trick for a while but not the car doesn't start again intermittenly. It seems like if I don't drive it enough one day I wake up and go to get in and go to school and my battery is dead.
Please help?

Tonight when you park the car - check the light where the ignition key goes in. I have had this same MY and model car experience a bad SWM (steering wheel module) and keep this light on when the car is not locked by the remote.

This was enough to drain the battery and eventually kill it. With the battery replaced and the car locked every night we have avoided replacing the expensive SWM. The issue was located using a parasitic draw test.

I had the same problem, it was the alarm system due to corrosion. I disconnected the fuse for the alarm system and now I do not have the battery drain

Hey there beamason61 thanks for the reply! Unfortunately that fuse has already been pulled. I actually think I might have two issues going on here. The sunroof wouldn't open before when we had the problem but the sunroof was an intermittent problem and the battery would always die when the car wasn't driven for a day or two. Now that the alarm fuse was pulled it dies like every 5 days even if driven...
We haven't had time to do the parasitic draw test as my daughter is rarely home when I am.
I'll keep you posted. Any more ideas, please let me know.
Thanks!

Hey there again. I really need help. Besides the car dying every night I found other things that proceed the dying. If my daughter uses the AC and turns it off when she leaves the car for the night (locked with key) it still dies. I have already done the draw test on it and find nothing. The fuse for the alarm and moon roof has already been pulled. I did notice before that the moon roof only worked sporadically. The overhead lights inside the car work sporatically. I did have the alternator tested and they said it was giving a charge. Could it still be something inside the alternator? I really need to know because it $355 for a new alternator and it is non-returnable. Please help me put an end to this problems. We have this great (expensive) car with all of these problems.

Thanks BKM but we already did that. Any other suggestions? I'm at wits end.

How can multiple things (all different) keep killing the battery?

Have you tried pulling the ECM to reset it to see how it affects the Alarm Module if that is indeed the problem?
