How do you replace the hood release in a 1991 Camaro?

Answer 1

Well... Hood release latch? Or hood release cable? For the Cable:

Open the hood.

On the hood latch there is a thin wire on the engine-side. There is a small thin metal clamp-like piece holding the wire in place. I used needle-nosed piers to pull the top part of the clamp out, then pulled the wire up and out of its holder. Follow the wire along the engine bay and there are little plastic clamps holding the wire down. Unclamp those release the wire that way.

Then inside the car under the drivers side, there are 2 or 3 screws holding the plastic panel in place. Pull the panel off and take out the screws holding the hood release latch in place. Hold the firewall plug and gently tug on the cable until its out. Then, replace in reverse. Run the cable through, attach cable to the latch's holder piece, clamp wires back down and screw back in. For the Latch:

Just like the release cable, unhook the metal wire, then unbolt the couple bolts holding it in place. Replace in reverse order. That easy.
