I have a 2002 ls430, replaced the battery yesterday and now all the sounds inside the car do not work.

Their is no beep if the keys are left in the ignition while the door is open. The seatbelt beep does not come on, if a door is open or the lights are left on, there is no noise.

All the display lights work but their are no beeping sounds.

Thanks for anyone's help.

 

You can try checking for any bad fuses.

 

There is a **** inside the car that controls the volume/sound level of the beeps that the car makes - any chance that someone inadvertently turned that control?
