When I had my new head unit installed, the chime starting working. I like it, some think it is annoying though. : : My chime also doesn't work because the previous owner disconnected it. I actualy perfer to go with-out the chime but if you want it reconected, take out the lower section of the dash under the steering wheel. Do you see the speaker? There should be two plugs going into it. If both plugs appear to be in, push on them to make sure there tight. If one, or both of the plugs is loose, plug it back in. If this doen't work, I don't have any answers. Sorry, but I'm in a rush.
