sliding rear window "seal" is coming out???

i noticed the other night when it got opened then closed, the seal on the side without the latch was coming loose and when its closed it sticks out in front of the window now...how could i go about fixing this or am i gna have to get a whole new dang window??? thanks

 

You can stuff it back in there by hand but it's a pain. Use a butter knife, it helps. Mine will stick when I try to slide it on a hot day, I've found that when you open/close the rear slider, putting a little outward pressure helps keep that seal from dragging and pulling out.

 

thanks

 

Mine has done this ever since i placed a window sticker right in the middle sliding glass.... I just push it back in there but ive became to lazy to even do that...
