    I just bought my 2010 charger R/T.
    I am having some lighting issues.
    Overhead council drivers side map light will not work replaced bulb with led (yes I flipped it twice because I know they are polarized) nothing would work. Same with third brake light changed all the bulbs nothing bought an led replacement nothing .
    Checked fuses all are good .
    Possible suggestions??
    Thank you in advance I am grateful.

    No the over head was burned out and the third brake lights are not burned out either.

    No I had heard that updating it would help these issues before replacing it I was wondering if any body had heard of this .

    Interesting.....i wouldn't think that replacing the engine control module would fix light problems, but I am far from a mechanic or technician lol

    Everything is so complicated on cars these days.....

    But then, I'm so old,
    I remember being able to work on my car when I was a teenager.
    We didn't have electronic nothing. :)

    Now I just kind fo keep my fingers crossed.
