I have a question that I need to get an answer: I have a 1999 Chrysler 300M and the dome light comes on all by itself and kills my battery. I replaced the battery and it did it again. A mechanic told me that when you replace the battery on this car, you need to get it reprogrammed. Is this correct or is he just trying to con me out of $165. Is this correct?

I would think you would need to find out why the dome light is coming on. I'm sure it doesn't need any re-programming.

Where would the door sensor be located? I read something that says they go bad. Is this true? Because at times, when I drive and hit a slight bump, my dome lights flicker. Could this be the issue and if so, can I fix it myself?

I found this info. "There is a wire grounding out at one of the left or right reading lights in the rear seats above the rear doors. I have seen the screws that secure the lights short one of the wires out and cause the interior lights to come on. I recommend checking this first by removing both reading lights and seeing if the problem goes away. Look at the wires going to the lights for signs of the insulation being rubbed through by either one of the 2 screws that mount the lights."

Sounds like Tom has a good idea......also check door switches.
