Interesting....haptic motor failure or wiring issue is supposed to set an alert which isn't appearing for me...but PN is 84017512 if only for my own future reference. I'll track dwon the correct PN for the heated seat and then probably order some cushions and debate about leather or not. Mine is in pretty good condition. One thing i've noticed is there appears to be a difference in the heated seat function for those with AC seats and those without. So i'll dive down that rabbit hole at some point i'm sure
