My power windows, seats, door locks, and trunk opener abruptly all stopped working.I checked the 50A fuse under the hood, it was fine.I read online that it could be frayed wire under the seat, and checked that. I didn't see anything (and on a side note, even if it was a frayed wire and I unplugged the seat, shouldn't the rest of the stuff work? It still didn't). Any other ideas? Is there a relay or something obvious I might be missing?
