1997 Chevrolet Blazer hood latch

If the latch mechanism under the hood is broken and your not talking about the steel release cable? If you can get the hood up, you might try lubing the latch mechanism, if that doesn't work, replace latch mechanism.

If your having trouble getting the hood up, you might try removing the front grille, then see if you can reach the latch mechanism?

I have the kind of hood that has to be pushed down to get it to pop up to get to latch.. already broke part of grill too

Are you saying the handle in side the vehicle for the release mechanism is broke? If so, can you get ahold the steel cable with a pair of vice-grips and pull? Will the hood pop up a little? Sometimes it helps to have a helper stand at the front of the hood and pop the hood with palm of hand as you work the release cable.

Most vehicles have secondary release under front of hood, that you have to release. Is that secondary release broken? I can't see much from where here?

My latch is not broke, the cable is loose.when u pull the knob u can hear a noise, but it wont pop up. Always have a helper...loll

Without being able to look at it, I don't know what else to tell you?
