Another stab in the dark S80

Battery is only 2 years old (original one lasted 7 years!). So I know it's not the battery. I have come to learn that the black plastic box under the seat with the wires running to it is the "power seat controller". By the clicking I hear when I try to move the seat each way (front up and down, rear up and down, seat back up and down, and whole seat forward and backward) it sounds like there are multiple relays in this box (or at least one!)

I would like to know if I can test the controller, and/or test the individual relays inside it, or anything else I can do to help diagnose this problem.

I would hate to replace that controller (mucho $$$ I'm sure, plus software download at the stealer) if there is a simpler fix.

I'm thinking that because the seat usually starts working after driving the car a short distance, that this is caused by the vibrations/movements of the car that cause some bad connection to "connect again." Just a guess...

Also, has anyone come across a vendor in the US that repairs seat controllers?

Any ideas welcome, thanks.
