🔧 Focus - Rear Window Regulator Replacement

The rear window regulator is the mechanism inside the rear door that raises and lowers the glass. Replacing it means removing the rear door trim panel, disconnecting the glass from the regulator, swapping the regulator (and possibly the motor), then reassembling and testing.

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

⚠️ Safety & Precautions

• ⚠️ Support the glass with tape before unbolting it from the regulator.
• ⚠️ Turn ignition OFF and remove the key/fob from the car while unplugging door electrical connectors.
• ⚠️ If your A-pillar/door area has side airbags: do not power up the car with connectors unplugged.

📋 Before You Begin

• Park on level ground, ignition OFF, and lower the affected rear window if it still moves.
• Have painters tape ready to hold the glass up once it’s detached.
• Quick check: Confirm the problem isn’t a blown fuse by verifying the other windows work normally.
• Two quick questions so I can give the exact, correct steps for your Focus (and the correct fastener torque list):
• ✅ Which rear door are we working on: left rear or right rear?
• ✅ Did you buy a regulator with motor or regulator only?

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the door side and parts setup

• Reply with left rear or right rear.
• Reply whether your new part is with motor or regulator only.
• Once I have that, I’ll provide the exact Focus-specific procedure including the correct torque points.

✅ After Repair

• Verify the window moves smoothly up/down and seals fully at the top.
• Listen for clicking/grinding (usually means the glass isn’t seated in the clamp correctly).
• Recheck that the door lock, speaker, and window switch all work.
