Okay, I've got news.
I looked at a Fiero parts car in my yard to see how the hood latch was supposed to work. Wouldn't you know it, this latch also had an issue. Fortunately, the hood was
not latched shut on this Fiero... which was a good thing as the latch assembly was badly corroded and impossible to operate. I removed the latch from the car to have a good look at it, and it turned out the lower of the two pivoting mechanisms was immovable. I've used a couple of images to show which pivot point I'm referring to. (The rivet can actually only be seen on one side of the assembly.) A red arrow shows which direction this piece needs to go to unlatch the hood. This piece was rusted solid on the parts car latch. I don't know how the heck the hood could ever have been opened (
if it had been latched shut) with that mechanism rusted so badly. IMO, the clever tool that
skitime designed and discussed in
This thread would
not have worked to trip open this latch. However, that tool might work just fine if the problem was limited to broken release cables.


Now that I had more of an idea of how the hood latch worked, I decided to try one of the simpler suggestions mentioned a couple times earlier in this thread.... hitting the hood while pulling the release. I now knew the latch was positioned dead center, 4.5 inches from the back of the hood. I put a 6"x12" piece of half inch plywood over this area and first gave a couple of good whacks with a rubber mallet
without using the release lever. I then pulled the lever with my right hand while using the mallet with my left hand. One good whack... and success! The hood popped open no problem.

I opened and closed the latch several times (using something
other than the hood, just in case) and it seemed okay, so I closed the hood. It now opens up fine, no whacking with a mallet required.

Thank-you to everyone who posted in this thread. This forum is such a good resource of Fiero information.
