I have a 2002 C-320 wagon that has power seat issues. It started about a week ago. It will move in any direstion EXCEPT back. I have moved the seat in every direstion ana onec, I was able to get it to go back. But, when my wife drove it, she moved the seat forward and my kenns ate wedged against the dash. Does anyone have a suggestion? I've owned it for 2 years and it has less than 59,000 miles. this is my only problem so far.
