I change my turn signal lght bulb and now my dash & rear lights don't work : when I open the door there's a beeping chimes that stays on
I was working in my signal lights and my dash & rear lights don't turn on on 2003 Buick Regal
Check the tail light fuse, are the front park lights working? The dual element bulb works with both tail light and turn signal. Check the bulb you installed for a problem. The dash lights are powered through the tail light fuse as well.
Make sure your bulb was the right one.
