đź”§ 4Runner - Front Window Regulator Replacement
Replacing the front window regulator on your 4Runner involves removing the interior door panel, securing the glass, unbolting the regulator, and reinstalling the new unit. There are a couple common part/side variations, and I want to keep this 100% correct (including factory torque specs).
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours (per door)
⚠️ Safety & Precautions
- ⚠️ Keep hands clear of the window rails and scissor/cable mechanism; it can pinch hard.
- ⚠️ Support the glass before unbolting it from the regulator so it doesn’t drop.
- ⚠️ Turn ignition OFF and keep the key away while your hands are inside the door.
- ⚠️ If you unplug the airbag-related connectors (some doors have side airbag wiring), disconnect the battery negative terminal first and wait 90 seconds.
đź”§ Required Tools
You'll need the following tools for this repair:
- 10mm socket
- 1/4" ratchet
