What doesn't work on your Discovery?
Cruise control, rear sunroof, (sealed with silicone by PO, probably leaked at some point,) ABS (I disabled it,) rear passenger window control. (Works from the console but not from the door.)
The vacuum pump seizes with lack of usage (bad vacuum lines) and weather and is in a tight spot, hard to remove with it's vibration isolators. I got mine to work after direct 12V, sewing machine oil and stiff plastic vacuum lines. No problem in three years. Not the best design but a religious moment (witness a resurrection) once it works.
