Default Help Needed - Electrical

Since I know that collectively, the members of this forum can solve anything, I've got a strange one for you all. Suddenly, the gas filler door button and the rear hatch button have both stopped working on my '03. I checked the fuses for both, and both are fine. The key fob still opens the hatch, so the problem is with the dash button. The puzzling part is that since they have separate fuses, I'm assuming the circuitry is not common, which makes me wonder why they both stopped working at the same time. I've tried with key in ignition, key out, vehicle on, vehicle off, every combination I could think of. Has anyone had any similar experiences, or can anyone suggest what to check next?

Only thing in common on both that I can find is both use G302 for grounding.
Here is the location.

Awesome, thank you! I'll try running a temporary ground to test this before I tear apart the interior. I'll let you know how it goes.

Both circuits go to a splice pack (SP302) and that splice pack is connected to ground…you will have to remove the bus bar off the top of the splice pack and check for bent pins or corrosion…below are the other circuits on that splice pack…are those items inop ??…if they are then the ground itself is bad.

No joy. The passenger seat pump works. The rear compartment lights work. The compartment lid latches work (with the key fob). The fuel door button and the compartment lid button on the dash don't work. I'll pull thee connector and look for bad pins, but everything was working, and I haven't done anything with the connector, so I'm not sure why those two items would stop working. I'm also going to try pulling error codes to see if anything pops up there.
