So a while back my Driver side power window button stopped working and my power door locks. Later i noticed the moonroof stopped opening and closing (don't know if same or seperate problem first time i checked it in a while). They worked perfectly before this. Does anyone know what might cause this?? Thanks for any help in advance

 

The sunroof gets disabled when the backup battery in the alarm module dies. Given that your vehicle is 14+ years old, that would be my first repair if you want the sunroof to work. Generally, I have not noticed that the alarm module disables the locks and windows so I would have to say that they are related.

The alarm module is not hard to change and I do recommend getting a new one from the dealer. There are articles out there where people have tried to solder in a new battery stack and I've been there and tried it. By the time that you catch this, the battery acid has eaten away the circuit board and the time to try and repair one is greater than changing it out.

 

thank you for the advise. I appreciate the guidance on replacing the battery as I have considered doing that. The alarm is what they call the siren module I believe. I believe I remember being told it needed replaced before. So I guess the focus now would be what is causing the driver side power window and power locks not to work.

 

Probably - I've always referred to it as the "alarm module". It is bolted to the structure on the RH side above the fender liner, behind the headlight.
