Very few have tried to refurbish one of those themselves. They aren't especially complex inside, but tend to be pretty well eaten up with corrosion which is what leads to failures like this. The only folks who I've seen do it themselves had three or four bad servos on hand and they were able to make one good one out of it.

The good (?) news is that you don't have to fork over $1600 for a new one. You can get a good used one on eBay for a few hundred. Who knows how long it will last, but I hate to say it, you're planning to sell the car...

Or, if you would feel better about it, you can get professionally rebuilt ones on eBay or from Performance Analysis Company. If they have one in stock, you can get a rebuilt one with a new plastic body for $300 or a rebuilt one with the more durable aluminium body for $600. You'll send them your old one for a core charge refund so they can rebuild it.

Lastly you can try your luck at the scrap yard. I found an aluminium servo there and got it for $15. The aluminium ones don't fail nearly as often.
