I myself have read through The stickied: "Replacing Lock Door Locks" thread fairly closely And I'm Still puzzled on how to Replace the Bulbs and How to check the switch that the bulbs and Dome light Run on. I've also Read the "Comprehensive lighting Upgrade" thread and again am quizzical on the bulb size. I don't mean to ::dead horse:: But I need some tips on troubleshooting. If I get enough help I will do a write up but Currently I am Fail. :1zhelp:
