I've come across this several times where the seats flip forward to allow the rear seat occupants out, until the system recognises the seat is back in the normal position, all it will allow is forward movement to assist the rear occupants exit.
Check around the area for a micro switch, this is what tells the seat control module, it might need cleaning, if not you could bypass it to resolve the issue.
In my opinion this is more likely than a relay, let me know how it goes.
I assume this has helped as you viewed a few days ago and have not had any follow up questions, therefore please could you rate ;)
