12v trunk socket failure, not the fuse

[mikeho]

TL;DR: Any tips to diagnose or fix a power failure with the 12v socket in the trunk? I’ve checked both fuse 61 and 71 (I believe 71 is the trunk) and both are intact.

I’ve been experimenting with different battery packs to extend the time on a dash cam. The latest experiment is with the EcoFlow Trail 300 DC. I was using an Anker car socket to XT-60 cable, which seems to be pulling a max 100W. The battery is 288Wh (90,000mAh), which is pretty big.

All of this to say that apparently, the rear 12v socket stopped working. I plugged in a car adapter that has a light when powered. No light. I have a cable with an LED display that tells the W/A/V. No power. I’ve checked the 20A fuse and it’s intact. Any ideas how to fix this?

The 20A fuses for the power ports are under the hood, you have to remove the frunk to get to it. Those are the ones you checked right?

Make sure the things you plug into the 12V socket draw less than 16A or about 200W to avoid blowing fuses.

Yes, I've checked fuses 61 and 71 in the fuse box under the frunk (it's pretty straightforward now to take out). I've had fuse 61 blow before, which connects to the port in the center console, so I knew where to check, but I was baffled that the fuse was intact. I even switched fuses 61 and 71 just to be sure my eyes weren't deceiving me; the front port still worked while the rear continued to be powerless.

I am currently having the same issue in my 2021. Any solutions yet. Fuses under the frunk tub are all good.

No solutions yet, unfortunately. When I get back, I'll probably take the car to the dealership and have them address it while I still have a little bit left on my extended warranty.
