Thanks, guys. Sorry, earlier I edited out too many details: I have a '93 Legacy 4-door sedan, Model L (2WD, auto trans., 4-cyl. engine). But you guys pretty much already knew the year & make, based on the presence of auto seatbelts. You guys are good!
Still haven't ruled out a fuse problem. The auto belts stopped working about the same time I installed a new powered antenna, which soon stopped working, too. Hope I didn't fry something. Where is the auto belt controller box on my car? In the trunk?
