So I found this video of a tour of an 82 F100, and this link should take you to the point where they pop the hood:
Thing is, when I pull the release in the cab, the hood does not pop up like that at all. In fact, it doesn't appear anything happens, so I'm thinking maybe that release mechanism is jammed. I can't even reach my hand into the area under the hood where the handle in the video is. It did work recently. The only thing I can put my hand on is the "box" that can be reached with my right hand through the grill, but I'm thinking that's just the other end of the mechanism that is activated from inside the cab.
Any differences in an 86 hood release, or is it the same as in this video?
I would try pushing down on the hood then pulling the handle again, if it opens lube the latch.
