Seat Control Modules

I know, this again?
I have read through most threads on this, and the "programming" part still eludes me.
Backtrack: Car is new to me. Passenger side is "dead", and both control modules were hanging off the wires when I got the car. Someone has been there before!
So, I did the swap test, and the problem follows this one module. Aha, one module is bad. So, after sending it out for a repair that proved unsuccessful, I decided to open the box and test. There is no obvious breaks in the tracks along the edge, where the hard plastic touches. And a meter shows zero ohm end-to-end for any track that is routed to the edge. Bizarre, I guess.
Here is the weird part: If I unplug the smaller connector to the module, then plug it back in again, the seat module works just fine (possibly with the exception of the heater). This can be repeated at will, it works consistently. This is with the key off the ignition. After a bit, it stops working, as when the key is inserted and moved to Acc. Does this mean it needs to be programmed in? Both modules look identical. Same part#, same number of "ports", 3 of them, including the middle memory port that does not have a corresponding connector on the passenger side. Both boxes have a sticker with "This part programmable". There are no messages in the cluster for any of this.
Pretty sure the local dealer would charge me an hour labor for this, so I wanted to be more informed before pulling the trigger. Thanks for any input.
Part# LJE2160AB/XXX
Guess: I have 2 driver modules, one original, and one from eBay.

While the modules are the same, the one in the driver position requires programming to be able to communicate with the other modules. Any correct part number module should work in the passenger seat.
I have an electronics background from many years ago and could not see any issues with the circuit board tracks but there were 4 that did not work.

If the module works intermittently as you describe then I'd conclude it's NOT a programming issue. A program fault would result in a continuous fault.
