Is it an electric pull down? If so, I was having the same problem for a while.. the part that sticks down from the hatch wasn't angled right to touvh it.. and the catch would stay down and it wouldn't latch unless I tripped the switch in it.. I re aligned the top piece and its been working fine... not sure if thats your prob though...
