Power Seats 2005 Cadillac STS

2005 Cadillac STSMy power seats and steering wheel not working. I checked the fuse and there good. I ran a jumper wire to the seats and they work. Where should I check next.


I would start with the fuse. If they are OK then trace the wiring harness. As for the steering wheel not working, I am going to assume you are talking about your Electronic Power Steering. Same thing there. Start with the fuses and go from there. I have provided the wiring diagrams for each circuit to help assist you.
