Automatic gear selector light is out which is needed at night for sure. A senior friend's 2006 Corolla is very low milage of less than 30k miles but this is what I thought to help her with. All other lights work fine. Gear selection works fine. Does the gear selector lighting interconnect with dash lights. They seem to work just fine. Seems a little early for a bulb to fail. What trail of connections or fusing should be checked first? Is it common for a switch interconnect to fail? There seem abundant internet visuals of diving into console to reach light bulb.
