ok, i have an 89. the headlights have not moved since I bought the car. I am rather tired of driving a bug eyed vette during the day.
I connected the motors directly to the battery and they work, so it must be the actuator module which costs more than i have right now. I was wondering if anyone has ever wired the motors directly to a switch inside the car so they can be controlled manually? if anyone as ever done this please let me know how you did it and how well it works for you. also for all the electronics people who may read this what are some of the problems i could face? overloading, etc?
thank you all..

Not neccesarily. It could be a break in the wiring either before the Actuator module or after it and before the headlight motors. I like to use a digital multi meter and a razor blade to make a small slit along various points in the wire's insulation to probe and check for continuity and voltage along the wire. A GM Shop Manual Schematic would help tremendously.
I suggest you diagnose the problem and repair it correctly. Keep Mickey Mouse outta the house. http://members.shaw.ca/agent86/Headlight%20Doors.pdf
Oops, as c4cruiser mentioned below, the link is for 84-87. I'll leave it here if anyone else needs the info.
As long as the motors work, it should be easy to fix. I had one that didn't work and it turned out to be a fusable link blown. The wire had rubbed on the frame and shorted out. Cost me about $3.00 to fix. Just follow the troubleshooting guide step by step and you will find the problem. All you need is a volt meter or test light.
There is a specific diagnostic routine in the Service Manual for problems with the headlamp doors opening correctly. It does sound like it's either fusible link F or G or the control module. The link posted however appears to be for 84-87 cars. These cars used individual relays for each motor and a separate isolation relay. The early motors work differently in that the polarity of the motor changes for opening and closing.
The later C4's use an enclosed electronic module that operates both motors. You might be able to find a used one at one of the Corvette salvage places. Vette2Vette or Contemporary Corvette. Probably much cheaper than buying a new controller.
