🔧 Elantra - Front Window Regulator Replacement

Replacing a front window regulator means removing the front door trim panel, supporting the glass, unbolting the regulator/motor assembly, then installing and adjusting the new unit so the window moves smoothly.

Before I lay out the exact step-by-step with the correct Hyundai torque specs and any variant notes, I need 2 quick details so I don’t give you the wrong procedure.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours (both front doors)

⚠️ Safety & Precautions

• ⚠️ Disconnect the 12V battery negative cable before working on the door wiring (power windows/locks and possible side-impact airbag wiring in the door).
• ⚠️ Support the window glass securely (it can drop suddenly and shatter).
• ⚠️ Keep fingers clear of the regulator scissor/cable path during testing.
