yea, I call'em rubber nipples
I havn't torn into one of those buttons yet, so I had no clue besides there being some type of mechanical tension...spring, nipple what ever...
If there is some type of short or issue in the memory seat module that is activating the heated seats- I would disconnect the drive door module. Obviously you will not have a visual indicator- if the heating element is on...but you should feel it, and it will also tell you that the door module is NOT what is activating the heated seats.
You will have a completely dead door during testing, but w/ no tech2- I think you can live w/ it for a bit.
