My driver side marker wont turn off

Marker light operation would be controlled by the switch, not the key in the on or off position. When turning the switch to the off position, do they go off? Is it possible an automatic lamp function is turned on which keeps the lights on for a bit? www.repairpal.com/repair-shops If you have further concerns, use that link to find a shop near you that you can visit and ask questions to directly.
