How do I fold down the rear seats on a 2004 ford taurus.

SOURCE: Rear seat won't fold down (60 part of 60/40 seat)

I had the same problem on my '03. The seats would not fold down using the latch release as I had always done. So I tried a combination of pulling up on the side latch AND the top latch and the seat folded down. It really doesn't FIX the problem but circumvents offending  defective part. I will use this method until it doesn't work then I might shell out the $$$$$ to the dealer.

There shouls be 2 straps inside the trunk at the top. Both on the driver side but one is for the left side and one for the right side seats. Pulling on the straps releases the 'lock' that should then allow you to pull down the seats from the back seat area.

THE SEAT RELEASES ARE IN THE TRUNK IN THE AREA WHERE THE SPEAKERS ARE NEAR THE EDGE OF THE TRUNK OPENING.

If you will open your trunk, you will see a round handle lever you pull on to release the seat. There should be one on each side. They are located near the top of your trunk.
