Rear Seat Removal
 

I purchased a used 2005 ES350. I notice that one rear seat shoulder harness has the buckle reversed. I assume I need to remove the bottom seat to unbolt the seat belt and slide the shoulder buckle off to turn it around. If correct. How do I remove the rear bottom seat?

There is no such thing as an 2005 ES350. I assume you either have a 2007+ ES350 or a 2005 ES330 (which has its own forum, as it is a completely different car).

Regardless of the year if the buckle is reversed you can fix it by folding the belt in the buckle and work it back to it's normal position. It is tough to do but can be done. That is how it got reversed in the first place. Even if you pull the seat you cannot reverse the buckle . If you did that you would end up with a twisted belt.
