I had the same problem. Luckily, the wire wasn't broken - the clip on the end that controls the lever at the bottom of the seat had come off. A simple re-clip and I was back in business. Check to see if it is broken or not before buying a new one. The link that gixxerphil posted is a great one, and the dealership is probably the easiest place to get a new one if needed. Definitely take the part number with you when you go!
