No interior lights when door is opened
I have a 2003 XLT I am having some issues with. When any of the doors or the lifgate are opened, the interior and exterior (mirror) lights will not come on. The lights will still not come on when the headlamp dimmer switch is used. However, the interior lights themselves can be turned on manually so I know the bulbs are OK. I have checked fuses and now have come to you guys for help......HELP! It is driving me crazy.
Thanks in advance,
