"Key left in" buzzer not working

[wjm]

Folks,

I just replaced my warning module (buzzer) because the driver door would not turn on the interior lights or sound the alarm. Also, the "lights on" buzzer would not work. Replacing it fixed everything.

My question is... I noticed that when I leave the keys in the ignition and open the door, there is no buzzing sound. Is there another part I need to look at?

Thanks!
