The drivers side power seat in my wife's 04 Expy does not move. When you try to move the seat front or back all you hear is a clicking noise. Any ideas on what this might be and how I would go about fixing....

Thanks in advance.....

 

ya had some problem on my 07 expo! found that the drive gear was striped and it was because the floor mat in back got shoved in to the railing and then we moved the set and striped the plastic gear or nylon what ever it is it was fixed by the dealer in just two trips to the dealer first trip was so they could see what was wrong and the second was so they could replace the gear after they ordered it form china or Mexico
