I tried holding the button for a long time and that didnt do it.
Your original post didn't mention memory seats or that that the seat back had the same issue.
Your seat memory module has lost its program and needs to be initialized or you have a bad position sensor. When either of these happens the motors will only engage for 0.5s per press of the switch. To recalibrate (learn) the module, you must drive the seat a step at a time to the maximum end of travel for each position, slide, recline, height and tilt.
If it will not recalibrate then it has lost a position sensor feedback (bad sensor). Also battery voltage must be above 10.5v or the memory module will go into sleep mode and ignore input.
