My driver seat base is bouncy it will go down when you sit on it and come back up when you get off it.

The seat base height adjustment motor is working however the angle adjustment for the front of the seat base motor is making a noise however not doing anything i believe this is why my seat is bouncy.

What part will i need to replace to get my seat angle working again.

i have removed the seat and checked and the seat base angle motor has a shaft with splines going in to the seat base metal frame however you press up or down on the switch it will keep on rotating and the seat base will not move.

Its like some part is broken not sure what ?
