The plastic gears in the headlight motors disintergrate after time. I searched on the web and found someone who sells a gear replacement kit for around $20. It came with instructions and I pulled out each motor and opened each up and after a powdery substance poured out of each motor, (the disintergrated old gears) I inserted the new gears reclosed the motors and reinstalled. To this day both my headlight motors work like new. It is easy if you are mechanically inclined at all. That's the only answer that I know of. You can leave the situation alone for now but eventually the gears will completely give out causing the headlights to stay up down or both. There is not limit relay; when you flip the headlights down does it sound like a spinning noise? If so, the motors have gone bad and need to be replaced. Autozone. Life Time Warranty.
If the motors run but lights do not come up you need to remove motors and the pull apart and put in small sections of hose these is detailed info on thirdgeneraton.com
If you go to corvettemagazine.com and click on there tech link they had an article that tells you step by step with pics how to repair the headlight motors
Electric headlight motors need replaced.

Don't replace the headlight motors, you'll only be wasting your money. Instead, just rebuild them by buying the headlight motor rebuild kit. Check out these links. http://www.bfranker.badz28.com/headlightfix/ http://www.rodneydickman.com/index.html

It is possible that you broke the motors when you forced the covers open. Try turning the headlights on and off and listen to see if you can hear anything from the motors. If you do, check to make sure that the connecting rod between the covers isn't broken.
If the motors are working, then there has to be a problem between the motors and the lights. If they are only "working" though if you bench test them, and they don't actually do anything when you turn on the lights, then there must be an electrical problem such as a break in a wire or a bad ground to the motors.
Mine did the same thing and I worked the stalk on and off a bunch of times and the problem went away, I have been told this happens because I almost never drive at night and never turn lights on, mine also would not turn lights on when this was happenning
They may just need the "cobwebs" worked out by using the manual "emergency" knobs located on the back of the headlight motors. You can do this by turning them on, opening the front hood, and then turning the knobs in the indicated direction. It takes a while though. If they still don't move after trying this a few times to free things and adjust the brushes, then you may need to repair, rebuild, or replace the headlight motors. F-Body cars of the same generation used the same motors, but the left/right were switched. There are several repair kits available online, as well as repair instructions. You can look on various Fiero community websites, or see what Rodney Dickman currently has available. I'm not going to link anywhere because I don't know if it will violate the terms of usage here, but try searching on the web. Good luck!
