Or you can rebuild it yourself
first gen motors have a plastic coupling that always breaks. To take the motor apart you just need to unbolt the headlight assembly. Takes like 5 minutes. Then you need to unplug it from the car. When the assembly is out, you can easily unbolt the headlight motor from it. Then drill out the rivets. When you open the casing up, don't be surprised if you see what looks like crayon shavings all over the place. That's what's left of your coupler. It takes a lot for the gears to strip, because they are nylon. If you let the motor run enough, you will eventually strip out a part of the gear.
When you get the assembly open, inspect your nylon gear. If it's stripped, you can get a replacement. If it isn't stripped and the only thing wrong is a bad coupler, just make a new one. I made mine with JB weld, but the instructions I read just said to use hot glue. All you have to do is fill the gear up with jb weld, where the coupler used to be, and let it dry. Then buy some screws, but some grease in the gears, and screw it back together. Will be as good as new.
here's a link about the whole thing...

You can just unplug the wire for now and work on it over the weekend if you want. you'll just have a winking fiero until it's fixed.
