Started this post in the SL forum but haven't gotten much response thought I would try it here. 1995 SL320 both seats don't adjust at all using the power seat adjustments from any part of the seat switch. Nothing moves at any adjustment position nor the headrest. Both fuses are fine, I find it hard to believe that both seat switches would be bad and much less nothing at all work on either seat switch. Is there a relay that controls the seat adjusments? If so does anyone know which relay and where it is located? If anyone has any other suggestions let me know thanks.

seat control modules under the seat bottom cushions I once saw both fail at same time due to jump starting/battery charging issues

Are you sure the key is on if the doors are closed. The seats won't move until you open a door or turn on the ignition. I hope this is the problem as it is a cheap fix! Let me know as this was my first post.
