I'm helping a friend track down a problem with his drivers seat in his 2009 F350 SD, V10. It's not a KR truck, but seems to have all of the other bells and whistles. It does have memory mirrors and we're assuming memory seats.
Story is:
After replacing the factory stereo with an aftermarket stereo, the drivers seat no longer moves.

Seems somewhat coincidental to me, but with memory systems, might be related. I can hear relays clicking in the seat module (under drivers seat) when I try to move the seat with the switches, but none of the seat motions so much as twitch.
Is there a way to bypass the memory system so the seat at least moves again?
Anyone have the relevant wiring diagram?

Thanks all!

 

Check fuse F45 in the fuse box under the hood. It supplies the high current to the driver's seat module (DSM) to run the seat's motors. Power comes into the DSM on a GY-RD wire. Verify it.

Power ground for the DSM (and motors) is a BK-VT wire that goes from the DSM to a grounding stud/bolt in the RH A-pillar. Verify it also,

Check those items first.
