I have an 84 Vette and had a similar problem. Get a needle nose pliers. If you able, grab a hold of the cable which is just behind the hood release handle, grasp on to it firmly and pull it, but to to hard. Have someone help you to open the hood at the same time if you need to. ...................Matt B.

Take it to a body shop as they have to open then on wrecks.
There's a special tool that'll release the latch by sticking it in between the hood edge and windshield. Any Corvette shop or even a dealer should have this. I've seen it advertised in Vette parts catalogs.
There are hood tools. But if it is stuck, you might have to jack her up, remove the wheel, and back fender skirt. Then the fun begins. If it is broken at the hood connection, you will have to bend a metal rod to reach, and pull.

Bang on the hood while you have someone hold the release
== == there is a tool i saw in a catalog trying to find which one. that tool was for 1984-1996.but they do have emergency hood release cable that can be installed in 68-82 part #604-801 for $19.99
The air temperature sensor on the 1984 Corvette is located under the hood. It is under the air control bracket at the front of the intake manifold.

The hood latch is located up by the windshield. It opens backwards. The hood opens toward the front of the car rather than to the back like most cars. The hood release should be in the left side of the drivers seat compartment. Pull that to release the lock. Run your fingers under the hood lip by the bottom of the windshield and locate the secondary hood latch. Release the lock and pull the hood up and toward the front of the car. If one or both of the hood release cables are broken, Mid-America Motorworks sells a tool to aid you in opening it. http://content.madirect.com/pdf/609637.pdf
If you can still see the wire, use pliers and pull, it should release the hood.
