Not sure on the S430 but on the S500 its under the plastic cover in front of the windscreen on the passenger side of the vehicle. Check if you have a large plastic removable cover at the front of the firewall, if so, its under that. Not inside the vehicle - no room behind glovebox, so resides in engine bay if its like the S500.
remove passenger side signal front light first then passenger headlight and horn should be right behind below the side passenger signal light!
On my 2002 Nissan Xterra I had to remove 4 screws from the front bumper and wheel well and then I was able to get to the back side of the side marker light and remove the nut in order to get to the light bulb. i don't need to change just the bulb. The entire light assembly must be replaced. The reflector is broken. i cannot get wires to release.
easiest way is to partially remove the inner wing which will expose all the side bulbs.
In the engine compartment right on the back side of the corner light there is a ring with a spring that hooks to a tab. Unhook the ring and the corner light slides out
