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.
