Got 08 hhr ss had to replace side curtian air bags, well removed headliner and dome light assy. And cannot get dome light assy back up any tricks or how to's, seems simple like it snaps up but cant ? Puzzled

 

Had mine replaced yesterday. Mechanic had the same problem, can't get the clips to snap inplace. You have to remove the clear lenses (3) from the cover. Then you are able to snap the cover back inplace, then install the (3)lenses. Good Luck
