    Ive looked online for this problem. My map lights work by pressing them individually but not when I open any door or hatch. I have checked all fuses in the driver side dash and the engine bay. I have made sure the override switch was set correctly. The brightness dial works fine but putting it into the top clicked position does nothing.

    The only thing I havent done is check the purple wire going into the pcm.

    Any ideas? 2003 GMC Yukon SLT 4x4.
