: : Here is the data for TSB 76-81-09. Sounds like this is for after the wires have been cut by the moving seat.

: Thanks EW - guess that's not the rock'n seat fix. But hey - my lumbar pump shorted out months ago and I've been too lazy to look - maybe that's what happened! The seat slowly rocks back and forth and cuts through the wires - solution - protect the wires!
: Thank you very much for posting the TSB!

Thanks again EW. Apparently the dealer performed this TSB on my seat at some point, and I didn't know it! But, when they put it back together they switched two connectors feeding the lumbar pump. The result is blowing the fuse. Instead of finding their error they simply disconnected the connector and re-fused - result no lumbar pump and blown fuse if you try to plug it in.
I found the swapped connectors and it works fine now.
BTW this fix is not a great cure, the abrasion occurs just after the controls and the cover they installed just barely protects the wires at that point. I re-did the job and added several layers of duct tape to the offending frame edge. It could have worn through again. The only thing that saved it was the almost full roll of electric tape they used to install the cover.
I good note to all when working under that seat - you can swap connectors and cause a short. Mark them before taking it apart. Funny that they didn't put different connectors on to prevent this problem.
