'87's likely the intermittent wiper governor.
It plugs between the switch and the harness.
These are a PITA to access, but they are up inside the dash above the fuse panel.
Some people have had luck re soldering the connections inside, but I didn't.
Search "wiper governor" and you'll come across many hits with this same symptom.
Good luck!

Ok so I got off friday & tore into it. The box is called a governor switch. The local store don't have them the the dealership wants $135. I can't see paying that since I rarely drive my truck. I wonder if it will pass inspection if the wipers only work on high?

I don't know a thing about inspection in VA.
As I said above you can open it up and re-solder the connections inside.(no guarantee on how long that will last)
OR, you can go to the autoparts and get a 2 speed control switch, put that in your dash and connect it directly to the harness leaving out the governor.
