🔧 Altima - Front Window Regulator Replacement

The front window regulator is the cable-and-track mechanism inside the door that raises and lowers the glass. Replacing it involves removing the front door trim panel, securing the glass, swapping the regulator (and sometimes the motor), then reassembling and verifying smooth window operation.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours (per door)

⚠️ Safety & Precautions

• ⚠️ Keep hands clear of the window tracks and scissor/cable paths while testing.
• ⚠️ Support the glass before unbolting it, or it can drop suddenly.
• ⚠️ Disconnect the negative battery cable before unplugging the window motor (prevents accidental movement).
• ⚠️ Use trim tools—metal screwdrivers can crack the panel or airbags/wiring.
