How do you fix a retractable motor on a 1999 Corvette that is constantly running when the car is turned off?

If you mean the headlight motors, go to corvettemagazine.com and click on the technical link. they have the procedure with photos and you can get the bushings (use Delrin, not nylon) on eBay for less than $10 to do both. it takes about 1 hour per headlight opposed to paying $300 per headlight to have it done.
