Ford Repair: Interior light(s) do not come on when door is open, door switches, ford taurus

Question
Hi...I have a 98 Ford Taurus SE...When my door(s) are open, none of the interior lights come on...I checked all the fuses and they look fine...I wonder if I'm overlooking a switch or something?  Thank You

Answer
First, make sure the switch on the dome light is set to the DOOR position, it may be off. If that is not the case, then you have a GEM module and relays involved. May have to have the GEM checked for codes. Sometimes the door switches stick, but not all at once.
