GRAND AM FOG LIGHT STAYS ON

GRAND AM 2002 lower FOG LIGHTS stays on when the car is turned off.
Will stay on till it drains the battery.

I thought it was the switch, replaced and did not work.

Then tried finding exposed crossed wires, it was not it.
Had to unplug it, but now  "service light" stays on.

Electrician ran the code and it is related to the fog light, he could not come
up with a solution nor reset the "service light".

Any ideas?

Thanks
