🔧 Tucson - Rear Window Regulator Replacement
On your Tucson, the rear window regulator is the cable-and-track assembly inside the rear door that raises/lowers the glass. Replacing it requires removing the rear door panel, supporting the glass, unbolting the regulator, and installing the new unit.
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours (per door)
⚠️ Safety & Precautions
- ⚠️ Keep fingers clear of the regulator and glass while powered.
- ⚠️ Support the window glass before unbolting the regulator, or the glass can drop suddenly.
- ⚠️ Disconnect the negative battery cable if you’ll unplug door wiring (prevents accidental airbag/electrical issues).
- ⚠️ Use painter’s tape to secure the glass to the door frame to prevent cracking.
