I am looking for the same information. There has to be fuse for the power seat, but I can't find anything referencing it...

2G FSM says that the seats share the power windows fusible link #9.
I don't see an additional fuse in the diagram.

Fuse link 9 it's a 30 amp fuse

The problem is that my windows work but power seat bung has no power (but it used to have it )

I just might have to drive it through the lighter outlet.

check if the wire is frayed anywhere or corroded with possible water leakage, but if you have power to your windows the wire must be cut somewhere down the line.

Most commonly, the ground corrodes right underneath the seat. Can I ask what are you using to check power and ground and how are you doing it. I would assume you are using a DVOM probing the two pin connector coming out of the floor. IF you are doing that, you need to verify you have a good ground. Otherwise you will think you have no power when in truth you have a bad ground and you do have power. So please report back and we can decide where we need to start.
