First off, welcome to iRV2!
Second, you should add a "signature" to your profile. It contains whatever info you want; most people put info about their coach there, so they don't have to type it into each message. Instructions for adding a signature are

Re: Seat. Chances are high you accidentally disconnected the seat wiring. Look under the seat for a disconnected connector. If one is there, plug it back in.
If any connector is not disconnected, or the seat still refuses to move after reconnecting the connector, then you may have blown a fuse and/or pinched a 12V wire in the mechanism. I can't tell you where the fuse might be. A pinched wire should be easy to find.
