The one under the driver's seat.
OK, I give up. How do you open the **** thing?
I've taken out the seat and both batteries. The manual suggests it just folds down, but I'm pulling on it hard enough that my (cold) fingers hurt and the plastic is seriously bending. I'm at the point that I'm worried about breaking something (I'm not sure whether I'll break first or the van).
So, how do you open it?
