For anyone like me who wants to repair the factory antenna motor rather than paying $140 to the dealer ("We don't break that part down lower than the right rear quarter panel"!!!) or $80 for an aftermarket replacement motor with less power and reliability, after much searching on the web I came up with the following: The factory motor was a Hirschmann Auta 6000EL (also used in Mercedes). Take a look at the schematics at http://www.primenet.com/~odemer/hirschma.htm, (a little difficult to read, and doesn't include part numbers) or at http://www.antennaworld.com/amfm/tips/6000el.htm (very easy to read and includes part numbers). I just ordered what I needed from Odemer (818-846-6324), from a very knowledgeable gentleman. And for $24.50!!!
