Middle Row Sear Stuck - Not Sliding

[ssorej]

Hi

I've a 2011 Galaxy and middle seat on middle row won't slider the runner. I had a 2007 and one of the outer middle row seats stopped sliding, but that wasn't too big a pain as kids use middle seat to get to third row. My middle,middle seat won't slide back far enough to fold down.

 

Anyone had this and know a fix.

 

Thanks
