86 Spider Veloce - power window problem

It started when head lights went out because I kicked a wire that was hanging under dash, found where that went, I pulled fuse box down plugged in the wire, put fuse box back up and now windows wont work, P.S. they worked before I dropped fuse box, Please help.

I'd start by dropping the fuse box again and checking that all the connections in the back are secure. If you remove and reinsert them that sometimes help clean off any corrosion on the terminals. Do them one-by-one to avoid mixing up where they belong. And while you're at it, check the fuses.

Inoperative power windows in our cars is not unusual. It may be a coincidence that they decided to stop shortly after you kicked that wire...

In no particular order here are the things known to cause problems with the windows.
  • Broken wires inside the rubber boot from the hinge pillar to the door. Pull back the rubber boot to see if you can find a broken wire (but usually it is the wire strands inside the insulation). Sometimes wiggling the wires while pressing the switch will find the faulty wire.
  • Faulty switches - the internal contacts can arc & burn until they no longer allow electrons to pass.
  • Faulty fuses. Especially the bullet fuses used in earlier models - these can somehow look OK but fail to pass electricity. Since the fuses could be decades old it might be worth it to simply replace them all. For the bullet fuses I prefer the ones with brass strips vs aluminum strips. And, clean the fuse box contacts, too. Sometimes removing & replacing the blade type fuse is enough to scrap off a bit of corrosion and get things working again.
  • Old petrified grease in the window motor can be a problem. But usually that just makes them operate slowly.

If you are certain that both windows quit working at the same time, I'd focus in on the relay (I12 in the attached diagram). Triple check the connections in the back of the fuse box where the relay plugs in. I've seen cases where a terminal gets pushed out of position such that the wire appears to be in the right place but the terminal isn't actually making contact when the relay is plugged in. The terminals are supposed to be held in position by a small tab in the terminal. If that tab gets bent or pushed out of place the terminal will move enough to not make the connection.
