How can I open my hood without the wire on a 1992 chevy blazer s10?

You gonna have to ripped out the front to get to the latch-its gonna be a tough deal with.

if you look right where the hood latch is, on the rightside of the latch there will be a small wire the has a circle loop the the cable hooks to to pop the hood. just take a small but long flathead screwdrive go between hood and the grill and just push in on that circle the cable goes in and the hood will pop. its easy i do it all the time. you may need someone to push the hood down as you do that so it will pop easier.
