6 Point Seat controls question- 1985 911
 

I have a six Point Seat control on Driver side...I just changed the lower seat frame and all electric componants... I put the bottom seat frame, ONLY, back in the car , without the seatback , to check switches to be sure they work, the front and back of THE BOTTOM seat go up and down as they should, but I do not hear any movement when pressing 2 of the 6 buttons...
Should I at least be hearing something moving when hitting those buttons? am I not hearing anything because the back part is not connected to the bottom seat? Should the back upper tilt with electric controls? I can not remember if those 2 buttons tilt the back part of the seat or not...anyone know?:confused::confused::confused:

Like to add that this seat slides back and forth manually

Hope this all makes sense!! thanks for your help.
