Assumption: This covers either rear door; steps are the same, but buy the correct left (driver-side rear) or right (passenger-side rear) regulator.

🔧 Sportage - Rear Window Regulator Replacement

The rear window regulator is the cable-and-track mechanism that raises/lowers the glass. When it fails, the window may drop, move crooked, click/grind, or stop moving. You’ll remove the rear door panel, secure the glass, swap the regulator (and motor if it comes as an assembly), then reassemble.

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

⚠️ Safety & Precautions

• ⚠️ Keep hands clear of the regulator cables and scissor points; they can pinch hard.
• ⚠️ Support the window glass with tape before unbolting it so it doesn’t drop and shatter.
• ⚠️ If you unplug any door electrical connectors, disconnect the battery negative terminal first to reduce risk of setting warning lights.
• ⚠️ Don’t turn the key ON with the door switches unplugged.
• ⚠️ Wear gloves—inner door metal edges are sharp.

📋 Before You Begin

• Park on level ground and keep the rear door fully open.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear door switch panel

• Use a trim removal tool set (specialty) to gently pry up the window switch panel from the armrest.
• Unplug the switch connector(s) by pressing the locking tab with a pick tool.

Step 2: Remove hidden screws from the door panel

• Use a small flat-blade screwdriver to pop off the small screw covers in the pull handle and/or behind the inner door handle area.
• Remove the screws using a Phillips #2 screwdriver.

Step 3: Release the door panel clips

• Start at the bottom edge of the door panel and use a trim removal tool set (specialty) to pop the clips free one-by-one.
• Pull straight out to avoid breaking clips.

Step 4: Lift off the door panel and disconnect cables/connectors

• Lift the door panel upward to unhook it from the top window ledge.
• Unplug any remaining connectors (speaker/courtesy light) using a pick tool.
• If equipped with an inner handle cable: rotate the cable housing out and unhook the cable end using needle-nose pliers.

Step 5: Remove the vapor barrier (water shield)

• Carefully peel back the vapor barrier using a plastic scraper.
• If the butyl sealer strings, cut it cleanly with a razor blade or plastic scraper.
• Don’t tear it—water leaks can happen.

Step 6: Secure the window glass

• Use painters tape (1.5") to tape the glass to the door frame (two long strips on the outside, over the top, and onto the inside).
• If the glass is dropped, lift it by hand to full up position and tape it securely.

Step 7: Unbolt the glass from the regulator

• Through the door access holes, locate the glass clamp/fasteners.
• Remove the fasteners using a 10mm socket with a 6" socket extension.
• Torque to 9 Nm (80 in-lbs) on reassembly.

Step 8: Unplug the window motor and remove the regulator assembly

• Unplug the motor connector by pressing the lock tab with a pick tool.
• Remove the regulator mounting bolts using a 10mm socket, 1/4" ratchet, and 6" socket extension.
• Carefully maneuver the regulator out through the largest access opening.

Step 9: Transfer the motor (only if your new regulator doesn’t include it)

• Remove the motor screws/bolts using a Phillips #2 screwdriver or 10mm socket (varies by build).
• Install the motor onto the new regulator.
• Torque to 6 Nm (53 in-lbs).
• Keep fingers off the cable drum path.

Step 10: Install the new regulator and tighten mounting bolts

• Position the new regulator into the door and start all bolts by hand.
• Tighten with a 10mm socket and torque wrench (in-lb or Nm scale).
• Torque to 9 Nm (80 in-lbs).

Step 11: Reattach the glass to the regulator

• Lower/raise the regulator carrier as needed by temporarily reconnecting the switch and battery (keep hands clear), then disconnect again once aligned.
• Install the glass fasteners using a 10mm socket.
• Torque to 9 Nm (80 in-lbs).
• Remove the painters tape (1.5") once the glass is secured.

Step 12: Reinstall vapor barrier and door panel

• Apply vapor barrier butyl seal tape where needed and press the barrier firmly into place.
• Reconnect all connectors and the inner handle cable (if equipped).
• Hang the door panel on the top ledge first, then press clips in around the perimeter.
• Reinstall screws using a Phillips #2 screwdriver and snap the covers back in.
• Reinstall the switch panel using your hands (press straight down).

✅ After Repair

• Reconnect the battery negative terminal using a 10mm socket.
• Test the rear window: full up/down several times and confirm it tracks straight and seals at the top.
• If the auto-up/down or pinch protection acts strange, “relearn” by holding the switch fully down for 3 seconds, then fully up for 3 seconds.
• Check for wind noise or water leaks around the vapor barrier and window seal.
