Fixing One or More Broken Power Windows: Electrical Issues

If pressing the power window button not only fails to move the window but makes no noise or any indication at all that anything is happening, then electrical power probably isn't getting to the regulator assembly. If all your power windows stopped working at once, an electrical problem is almost certainly the culprit. It's highly unlikely that four separate motors would fail at the same time - but none of them will work if they don't receive power.

If that's the case, you'll want to check the fuses and relays associated with the faulty power windows. If a fuse has blown or a relay has worn out, replacing it could be all that it takes to fix your issue! However, if the new fuse or relay blows again quickly, a more significant, underlying electrical issue will need to be addressed by a professional.

Finally, sometimes it could be the switch or button itself that has worn out, or has become disconnected from the electrical system. A trained technician will replace the switch and any broken electronics associated with it.

Removing trim pieces, door panels, speakers and wires from the door in order to access the regulator assembly or switch can be difficult for an amateur to do, and you might accidentally break plastic trim pieces in the process. If you need a helping hand on this task, the factory-trained professionals at Mike Shaw Subaru in Thornton can handle it for you at a price competitive with local competitors, and with a quality of service you just won't find anywhere else.
