Hood Latch on 89 s-10

I have a 1989 s-10 that I am trying to open the hood on so I can check the fluid levels and so forth however when I pull the hood release on the inside of the truck it doesn't seem to unlatch the hood so I can open it. I have sprayed some wd-40 into the latch to see if that would help it hasn't I am trying to find the answer to this so I can either fix it or my husband can when he gets home from sea next week. Thank you for any help

Sometimes they stick...have someone pull the release while you push down on the hood...a little wiggle of the hood should release it.
