I discovered a leak next to the passenger rear seat. It seems to be leaking from the wheel well. How do you remove the rear bench seat? The manual says there are 2 bolts but I can't see any.

This write up covers removing the rear seat.

Thanks Danthurs. I had already figured it out. Just like most rear seats I have removed. On to the leak--if there is a gap in the metal on each side next to the seat bottom ( from the factory, where wires come through), does that mean I have a hole in the wheel tub or could it be a drain problem?

Can you post a picture?

Likely a hole in the wheel well. Remove the tires and take a look.

Do you have a sun roof?
