I have a 2007 GL450 and since I have gotten it the right fog light has been defective, I decided to buy new bulbs and replace. The new bubs worked fine on the left side but the right is still not working. I checked the voltage and it shows -11.8 on red positive/black negative, when i switch the wires on the amp meter it shows 11.8 on black positive/red negative.

I cannot locate a fuse for the fog lights.

I hope someone has an answer for me.

Thanks
