Hi Mistral. Unfortunately, there is no way to accurately diagnose this blindly over the Internet.Hi.
Why suddenly the EASY ACCESS seat option is no longer working everytime I remove or insert my key in, the seat won't move back when the key is out and wont move forward when I put the key in. Everything is working manually... All positions.
Thanks.
I would recommend you try to reset the memory seat buttons to your desired positions again to see if that helps.
If it does not, you will need to have it diagnosed by your Ford Dealer.
Let us know how you make out and good luck.
