Hello, I am new to the forum. I have a 2004 GX470 and I have a drivers side foglight that is getting condensation inside. Probably need to replace it but does anyone know if any year Toyota 4Runner foglight assembly will fit the GX470?

I would try to remove the assembly as if you are changing the bulb and then try to blow it out with compressed air or a hair dryer before replacing it. Perhaps the bulb seal is allowing moisture past and you just need a new seal.

Sorry for the late reply, but the 4Runner (any year) fog light will not fit the GX470. If you are talking about the 03-05 4Runners, the fog light assembly they have also includes their turn signals also but with the GX the fog light assembly only consists of the fog light.
