How to Replace a Rear Window Regulator on a 2018 Honda Pilot (Rear Door)
Step-by-step rear door panel removal, glass support tips, required tools/parts, and installation checks


š§ Pilot - Rear Window Regulator Replacement
On your Pilot, the rear window regulator is the cable/track assembly inside the rear door that raises and lowers the glass. Replacement involves removing the rear door trim panel, supporting the glass, unbolting the regulator, and reinstalling everything without damaging the glass or door clips.
Before I give the exact, trim-correct steps + torque specs, I need 2 quick details: Which rear door (Left/Driver or Right/Passenger)? And are you replacing regulator only or the regulator + motor assembly?
Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours (one door)
ā ļø Safety & Precautions
- ā ļø Keep hands clear of the window tracks while powered.
- ā ļø Support the glass with tape before unbolting it from the regulator.
- ā ļø Donāt turn the window switch on with the glass detached.
- ā ļø Use trim tools to avoid breaking door-panel clips.
- ā ļø Battery disconnect is not required, but remove the key fob from the vehicle and keep the ignition OFF while connectors are unplugged.

š© Required Parts
HowToo sells all the parts you need for this repair:
- Rear window regulator (correct side) - Qty: 1
- Rear window motor - Qty: 1 (only if not included with regulator)
- Rear door trim panel clips - Qty: 4-10 (as needed)
- Butyl door vapor barrier adhesive strip - Qty: 1 (as needed)
š Before You Begin
- Park on level ground, shift to Park, and turn the ignition OFF.
- Lower the rear window to about halfway if it still moves (this typically exposes the glass-to-regulator fasteners through the access holes).
- Have painterās tape ready to secure the glass to the door frame.
- If the window is stuck UP, plan to support the glass immediately once the panel is off.
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm door side and part style
- Reply with: Rear Left or Rear Right.
- Also tell me if your replacement part is regulator only or regulator + motor (some come as one unit).
- Once confirmed, Iāll give the exact fastener locations and Torque to XX Nm (YY ft-lbs) specs for your Pilot.
Step 2: Remove the rear door trim panel (general outline)
- Use a plastic trim removal tool set to pop off the small trim covers hiding screws (typically in the pull handle and near the latch area).
- Remove exposed screws with a Phillips #2 screwdriver.
- Use a plastic trim removal tool set to release the panel clips around the edges, then lift the panel upward to unhook it from the window ledge.
- Disconnect electrical connectors using a pick tool to lift locking tabs gently. Donāt yank on wiring.
Step 3: Peel back the vapor barrier
- Use your hands and a plastic trim removal tool set to peel the vapor barrier back slowly.
- If the adhesive is stubborn, warm it slightly with cabin heat and work it loose. Keep it clean for reuse.
Step 4: Support the glass
- Apply painterās tape (1.5" wide) from the outside of the glass over the top of the door frame to hold the glass up.
- Add 2-3 long strips spaced apart. More tape is safer.
Step 5: Detach the glass from the regulator
- Through the door access holes, loosen/remove the glass clamp fasteners using a 10mm socket, 1/4" drive ratchet, and 6" socket extension (1/4").
- Confirm the glass is secure with tape before the last fastener comes out.
Step 6: Remove the regulator and motor
- Unplug the motor connector (if equipped) by releasing the lock with a pick tool.
- Remove regulator/motor mounting bolts using a 10mm socket, 1/4" drive ratchet, and 6" socket extension (1/4").
- Maneuver the regulator out through the access opening carefully. Watch sharp door edges.
Step 7: Install the new regulator
- Position the new regulator in the door and start all bolts by hand to avoid cross-threading.
- Tighten using a 10mm socket and 1/4" drive ratchet, then final-tighten with a torque wrench (3/8" drive, inch-lb/low Nm capable) to Torque to XX Nm (YY ft-lbs) (after you confirm side/part style).
- Reconnect the motor connector until it clicks.
Step 8: Reattach the glass
- Lower/raise the regulator carrier (if needed) by briefly turning ignition ON, then OFF, so the clamp aligns with the glass holes.
- Attach the glass to the regulator using a 10mm socket and 1/4" drive ratchet, then final-tighten with a torque wrench (3/8" drive, inch-lb/low Nm capable) to Torque to XX Nm (YY ft-lbs).
- Remove the painterās tape (1.5" wide) only after the glass is clamped.
Step 9: Reinstall vapor barrier and door panel
- Press the vapor barrier back into place; add butyl door vapor barrier adhesive strip if it wonāt reseal.
- Reconnect electrical connectors, hang the panel on the upper lip, then press clips in around the perimeter.
- Reinstall screws with a Phillips #2 screwdriver and snap trim covers back on.
ā After Repair
- Turn ignition ON and run the rear window fully down and fully up 2-3 times.
- Listen for binding/clicking; the glass should move smoothly and seat evenly at the top.
- Verify the window switch, child lock behavior, and door lock/unlock functions.
- Check for air/water leaks by inspecting the vapor barrier seal all around.
