I installed a new stereo a few weeks ago - Kenwood unit. It works great - as long as I don't open the door while it's running. When I open the door while its running the stereo will often stop - the display is still lit, but no music from either the tuner or CD. Ussually it's the passenger side front door, but occasionally the drivers side door will do it also. On rare occasion, opening and closing the door causes it to start working. I suspect this is somehow related to the switch for the dome lights. Opening the passenger side front door sometimes doesn't turn on the lights, and sometimes it does just for an instant. And the back doors don't turn on the lights at all. So my first order of business to to see if I can clean those switches and see if that helps - but any other suggestions are appreciated!
