I had the exact same problem on the same car. Tried two new cables - still no good.
I managed to buy a 2nd hand unit - works perfectly attached to my drill, however I haven't refitted the dash yet (another job), so I won't know if it works properly until it's in place.
I think the point about over lubrication is spot on. My old one was smothered in oil inside.
