Wiring diagram

Hi, I have a 1993 Pontiac Grand Prix STE. It has the 3.4 V-6 and 131,000 miles. It is a 4-door. I need a wiring diagram for the power seat circuit. The switches do absolutely nothing. Nor can you hear the seat motors making any noise. I can not locate a fuse for the seats or a relay. The seat controls are located on the lid for the center console. I used a test light and am not getting power on any wire in the connections located under the center console. I purchased a Haynes manual and it gives me all wiring diagrams except the power seat diagram. Thank you in advance for your help. Dennis.
