If that relay fails (unlikely) or becomes loose in its socket (far too many reports of this) both seats will fail to work. There was a short thread on this subject here a couple of weeks ago. It's also possible (but less likely) that the main computer has failed; one of its functions is to deliver a signal to the pilot relay whenever the ignition is on *or* a door is open; if that signal line isn't working as it should the seats won't work. If it's intermittent, that suggests that the relay is loose and hasn't fallen out entirely. Look under the left seat for the relay and press it back into its socket. While you're there, you might want to use some of the All-Purpose Attachment Product (i.e., duct tape) to make sure that the relay stays where it should. It will be easier if you don't have the "position memory" seats; if you do, the control unit can make it almost impossible to find the relay without taking the seat apart or dropping the control unit from its attach points. I'm speaking from recent (two days ago) experience; in my '97 900 the seats were completely dead, and in a position that made it very difficult to see anything. Joe Morris
