🔧 Wrangler - Rear Window Regulator Replacement
Rear window regulators are the cable-and-track assemblies that raise/lower the glass. On your Wrangler, “rear window” can mean the rear liftgate glass (tailgate window) or the rear door glass (4-door Unlimited). I’ll cover both procedures—use the one that matches where your stuck/broken window is.
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours (per window)
⚠️ Safety & Precautions
- ⚠️ Disconnect the negative battery cable before unplugging window motors to prevent shorting or accidental movement.
- ⚠️ Support the glass with painter’s tape (or have a helper hold it) before loosening regulator bolts—glass can drop suddenly.
- ⚠️ Wear cut-resistant gloves; door and liftgate inner metal edges are sharp.
- ⚠️ Do not pry on the glass—only on trim panels and clips.
🔧 Required Tools
You'll need the following tools for this repair:
- Safety glasses
- Cut-resistant gloves
- 10mm socket
- 13mm socket
- 1/4" ratchet
- 3/8" ratchet
- 6" extension
- Trim clip removal tool
- Phillips screwdriver #2
- Torx T20 screwdriver
- Torx T30 screwdriver
- Pick tool
- Painter’s tape (2" wide)
- Magnetic parts tray
- Torque wrench (in-lb)
- Torque wrench (ft-lb)
🔩 Required Parts
HowToo sells all the parts you need for this repair:
- Rear window regulator assembly - Qty: 1
- Rear window motor - Qty: 1 (only if not included with regulator)
- Door/liftgate trim panel clips - Qty: 1 set (recommended)
- Water shield butyl tape - Qty: 1 (recommended)
📋 Before You Begin
- Park on level ground and remove the key.
- Lower the problem window (if it still moves) to about halfway so you can access the glass-to-regulator fasteners.
- Disconnect the battery: use a 10mm socket to remove the negative cable and isolate it so it can’t spring back. Negative is the “-” terminal.
- Have painter’s tape ready to hold the glass up once it’s detached.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Choose the correct procedure area
- If the stuck window is in the swing gate (rear-most glass), follow Procedure A: Liftgate Glass.
- If the stuck window is in a rear passenger door, follow Procedure B: Rear Door Glass.
Step 2 (Procedure A): Remove liftgate interior trim panel
- Use a trim clip removal tool to pop the liftgate trim panel clips loose around the edges.
- Remove any screws you find using a Phillips #2 or Torx T20 screwdriver (hardware varies by panel style).
- Lift the panel off and set it aside. Use a magnetic parts tray for screws and clips.
Step 3 (Procedure A): Peel back the water shield
- Carefully peel back the plastic water shield using a pick tool (don’t tear it).
- If the butyl (sticky seal) won’t re-stick, plan to use water shield butyl tape during reassembly.
Step 4 (Procedure A): Support the liftgate glass
- Use painter’s tape (2" wide) to tape the glass to the outside of the liftgate so it cannot drop.
- Add 2–3 long strips from glass to painted metal. More tape is safer than less.
Step 5 (Procedure A): Disconnect motor and unbolt regulator
- Unplug the window motor electrical connector by releasing the lock tab with a pick tool.
- Use a 10mm socket and 1/4" ratchet to remove the regulator/motor fasteners.
- Use a torque wrench (in-lb) for installation: Torque to 90 in-lb (10 Nm).
Step 6 (Procedure A): Detach glass from regulator and remove the regulator
- Locate the glass-to-regulator clamps/bolts through the access holes.
- Use a 10mm socket to loosen/remove the clamp bolts, then confirm the glass stays supported by tape.
- Remove the regulator assembly through the access opening, rotating it gently to clear edges.
Step 7 (Procedure A): Install the new regulator and reconnect the glass
- Position the new regulator in the liftgate and start bolts by hand to avoid cross-threading.
- Use a 10mm socket to snug the fasteners, then Torque to 90 in-lb (10 Nm).
- Reconnect the glass to the regulator clamps using a 10mm socket, then Torque to 70 in-lb (8 Nm).
- Plug in the motor connector until it clicks.
Step 8 (Procedure B): Remove rear door trim panel
- Remove trim screws using a Phillips #2 and/or Torx T20 screwdriver (commonly behind the pull handle and near the latch area).
- Use a trim clip removal tool to pop the panel clips loose around the perimeter.
- Lift the panel upward to unhook it from the window ledge.
- Disconnect any electrical connectors using a pick tool to release the lock tab.
Step 9 (Procedure B): Peel back the water shield
- Peel back the plastic water shield carefully; use a pick tool to separate sticky butyl without tearing.
Step 10 (Procedure B): Support the door glass and detach it from the regulator
- Tape the glass to the door frame using painter’s tape.
- Through the access holes, use a 10mm socket to remove/loosen the glass clamp bolts.
- Torque for reassembly: use a torque wrench (in-lb) and Torque to 70 in-lb (8 Nm).
Step 11 (Procedure B): Remove regulator and motor
- Unplug the motor connector using a pick tool.
- Use a 10mm socket with a 1/4" ratchet and extension to remove regulator fasteners.
- If the motor is separate from the regulator, remove the motor fasteners using a Torx T30 screwdriver.
- Torque for regulator fasteners: Torque to 90 in-lb (10 Nm).
Step 12 (Procedure B): Install new regulator (and motor if needed)
- Set the new regulator into the door and start all fasteners by hand.
- Use a 10mm socket to tighten, then Torque to 90 in-lb (10 Nm).
- If transferring the motor, install it using a Torx T30 screwdriver and Torque to 90 in-lb (10 Nm).
- Reconnect the motor connector until it clicks.
Step 13 (Both procedures): Reconnect battery and function test before reassembly
- Reconnect the negative battery cable using a 10mm socket.
- Cycle the window up/down while watching the regulator tracks (keep fingers clear).
- If the glass tilts or binds, loosen the glass clamps with a 10mm socket, align the glass, then re-torque: Torque to 70 in-lb (8 Nm).
Step 14 (Both procedures): Reinstall water shield and trim
- Press the water shield back into place; add water shield butyl tape if needed.
- Reinstall the trim panel: align the top edge first, then press clips in by hand.
- Reinstall screws using a Phillips #2 or Torx T20 screwdriver.
✅ After Repair
- Run the window fully down and fully up 3 times to confirm smooth travel.
- Listen for clicking/popping (often a mis-seated clip or misaligned glass).
- Check for water leaks after the next rain or a car wash—water shield sealing is critical.
