1. None of my interior door lights come on accept for my back left light. For my driver and passenger door the bottom door lights come on but the top interior door lights never come on unless I push the button to turn them on. As far as I know the bulbs are not dead.

2. The beeping sound when locking and unlocking my car is super quiet often times i dont hear it if something is going on outside. Is there a way to make the sound louder or is something "dying/fading" that I need to replace soon

 

There is an adjuster **** for the tone, the lights you turn on via the buttons is not the same one as via opening the door

 

Hope this may be of some help....

Thanks this helped a lot. I had to play with the switch a little to get the lights to work. I switched it to door and it didn't work at first but after switching it to on,off,door a few times then it finally worked
