The XYZ switch in my 2004 D2 stopped working. These use the new style switch which doesn't have the fingers in it. I pulled it off (and in the process managed to shear off the threaded portion at the end of the shaft) and opened it up and the same contact was a little burnt that is burnt in all the pictures I found online. I cleaned up the contact, smeared it full of dielectric grease, bolted it back together and re-installed it and it works great. But I'm not sure for how long. Standard Motor Products makes a replacement switch which I have found for around $450. Has anybody used one of these? Just wondering if they are any good.

EDIT: I also found a Wells LU408 at Advance Auto for $353.99. That's the lowest price I've found for any XYZ switch. Supposedly made in Germany. Might just go with that one.

 

I have no experience with XYZs from either of those suppliers, but I would personally not by a new one at this stage of my truck's life. Dismantlers like Paul Grant will sell and guarantee (for some period of time) used ones, usually ~$100.

I have a backup I pulled from a parts truck at a local boneyard for $10. If my XYZ fails I'll install the backup and rebuild the failed one. Or maybe I should go ahead and test/rebuild the backup now so it's ready to go. Or just go ahead and install it, then rebuild the current switch so I know I have a good backup on hand.

 

That was my other plan, but the used ones I saw listed online were more than $100. I considered getting one out of a junkyard in my area but they usually have the Discovery's sitting on the ground which makes accessing the xyz switch pretty tough. I'll see if Paul has any for sale.
