Do hope you will find it there, but somehow doubt it, (see my previous post).
When you find the relay, do check continuity, earths, condition of wires etc to the mechaanism.But you may find that the spring in the mechanism that the cogwheel rides over, which works the switch, is bust or the switch is sticky.
But I state quite categorically that the park switch may work differently.
Have you Googles "self-park switch Land Rovery Discovery series 2"? If not, I would !!!!!!!
Well I just did it for you. See this,

Amazing what you can find on the internet!
As I said, the switch in in the mechanism, under the point where the blades are turned by the arm. Not in the motor, nowhere else, exactly as mentioned in my first post.
Amazing what old skool stuff there still is on cars.
(Lots of peeps think
all WWs are worked by some kind of rocking mechanism, lol!)
