There are THREE screws (one is almost under the steering wheel o the back edge of the cover - toward the steering wheel end). The cover just prys off after that. The tilt motor is on the door side. Pull the side cover off the tilt motor to access the green gear. Pull off the nut, and fashion 2 small hooks from a stiff wire to gently pull out the gear. You will wnt to space out the gear (it meshs with the worm gear only on the very edge. I used a garden hose rubber washer behind the gear to space it out so the worm gear meshes completely with the green gear. Re-install the gear and nut, and you're done. For free!
I saw a video on youtube a while back that shows the fix - you can probably search and find it.
