My best suggestion is to take a good look at the configuration on one side and compare it to the other. The passenger side set-up underneath the seat is probably very similar to the drivers side.
Upon close inspection you will most likely find something amiss...you may have disconnected a guide wire or whatnot while vacuuming, or if there was someone sitting in the backseat behind you, may have dislodged something with their foot.
Take a close look at both sides and compare them, you will find something different I am sure. You will find what's wrong!
