seriously in need of an expert

MY2010 997.2 4S, I have removed nearly every fuse and cannot find the one connected to the footwell lights and/or the glove box light.

Any ideas?

The fuse chart does not indicate specifically a fuse for any of the interior lights. I'm a bit lost, and I think I've got zero power to the glove box light, but all the rest of the lights are working.

argh!

Did you check the microswitch on the back of the glovebox? I had the same problem (thought it was a fuse), but that's what it turned out to be.

I would try to measure the voltage BEFORE the switch, if possible.

So, you have zero volt between any pin of the switch and the ground? Then, the 12Volts is not coming to the switch....unless the switch is fed by the ground. I would have to check the wiring diagram to figure it out.

How about the voltage between each of the Bulb contact and the ground?

this may give you some indication of my level of understanding...

I stick the meter in both holes of the harness that attaches to the bulb housing, and I get nothing. I cannot speak to "ground" because I am completely ignorant. Is this hopeless without a service tech?

Near the fuses, on the fuse box, up and right corner, there is a red thing that will pop out if you short any of those contacts. Just push it back in and you will regain power.

btw, I'm not an expert...

Let me be more precise. The negative lead of your multimeter (black lead) must be connected to a big metallic bolt or something that touches the chassis of the car. Then with the other wire of your multimeter, you can measure different points. This way of doing is giving you an absolute voltage. For instance one of the wire of the switch (connected to your red multimeter wire) should read 12Volts. Similarly, one of the contacts going to the bulb should read 12Volts when the glove box is open.

Nothing more complicated than that.

Thank you. If it turns out to be that easy in this case, dinner is on me.

Wait, you're "seriously in need of an expert" because your glove box light doesn't work?

Okay, now I have done this. I get a reading of 12.19 volts at one of the metal conductors once it is plugged in to the wire harness. I cannot get a bulb to light, however. I feel like I am on Candid Camera. Coupled with the fact that I'm a technical ritard, this simple little BS issue is going to be my UNDOING.

By the way, the red thing in the upper right of the fuse box was out enough that I pushed it in a considerable distance, as if to reset it.

Either way, I seem to get voltage to the socket, and I have a handful of bulbs that I pulled from interior lights that were working, and I cannot get one of them lit.

I. Am. An. Idiot.
