Rear power window or door lock not working on your 2004 Honda Civic? In this video, I diagnose and fix a dead rear window and lock by replacing the rear door wiring harness—one of the most common failure points on 2001–2005 Civics. You’ll see a complete step-by-step walkthrough, including door panel removal, moisture barrier handling, harness routing through the door jamb, and proper installation of the factory replacement wiring. No guesswork—just a clean, detailed repair that restores full window and lock operation.
