I have a 2006 F-350 lariat crew cab. The back seats fold down so you can access the area behind the seat. For some reason my drivers side backseat will NOT fold down now. It used to flod fine now i cant get lever that releases it to move. Ive pushed pulled in every way on the seat and lever... Anyone else had this any help???

I know this is a little unusual but I cannot figure it out!

Thanks
Robert
