There are two latches on each side in front. Raise up on these (sometimes you will need a bar to get them loose). Then raise up on the front of the seat, then go in back and slide the seat back to get loose from back hooks. It is best to fold down the back of the back seat first. It is usually a two person job.
on back of the seat bottom cushion there are finger tabs, you must pull straight up or they will not work.
There is a heated seat module under the seat somewhere. I had the same problem, but it was under warranty, so the dealer did it.
