seat and mirror memory with key gone crazy

[95_ESi_Person]

I had to disable the seat position and mirror position memory in the truck because any time I'd unlock the car everything would move to a new position. Once in a while it would stay where I had it, but every other time the mirrors would go to completely crazy positions.

Any suggestions on possible problems?

And, I did press the button on the door to "save" all positions to my preferences, but that apparently didn't work.

Is there any hope, or should I just leave that function disabled?
