Update: I confirmed all connections are tight and voltage is as expected on various wires. I also confirmed that none are getting pinched or there is no flexing under the seat when I sit on it that is interfering with any connections.
I have now noticed that the power seat control works 100% when I am not sitting in the seat. When I sit in the seat, it cuts out immediately. When I lift my ass up off the seat, it works again within one or two seconds. When my wife (much lighter weight than I) sits in the seat, it works fine.
My new theory is that a short in the seat heating element on the cushion is interfering with the power seat controls. Could that somehow interfering with the memory seat module?
Is there a way that I can disconnect the seat heater element without removing or significantly dissassembling the seat? Does anybody know which wires under the seat would control that?
I am excited really hope I am on to something here. :-)
