Slider popped out

Unless part of the plastic slide has broken off, you can simply "snap" it back in place. Being careful you my need to use a little force but it should just snap back into the track.

Hi scott.
MrJLH is having problem posting, so he told me to post this for him:

"I've tried to respond to you several times. I'll try again. If it still does not go in, you best course of action is to take it to a dealer who does repairs. He will have the correct tools or know the trick need to snap it back in. Because I don't have it in front of me, I can't give you any better advice. This is your best option at this time.

Sorry I couldn't be of more help. Good luck"
