Hi sir , how are you today
has the memory seat fuses been checked , they will be behind driver driver rear seat fuse box ?
can you tell me if the steering wheel function is working , will steering moves in /out, up & down ?
can you tell me if you lock the car from driver side door using the key in door key lock cylinder and you unlock with the key will seat go all they way back ?
do you hear the chime sound when you tried to set the a memory postion by pressing the key and holding it ( is the chime sounds it does you can still hear ?
most common cause are the 5 potentiometer resistors located under the seat are bad
taking the seat out will be best I found to replace.but the is other things need checking
1- driver door module
2- poor connection to motors or potentiometers
3- wiring harness to the seat the seat
4- poor connection to body processor module
