🔧 Savana - Front Window Regulator Replacement

The front window regulator is the mechanism that lifts and lowers your door glass. When it fails, the window may move slowly, bind, fall into the door, or stop moving entirely. You’ll remove the inner door trim, secure the glass, then swap the regulator (and motor if included).

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

Assumption: Your Savana has power windows and a bolt/rivet-in regulator assembly.

⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before working inside the door to prevent accidental window movement and to protect electronics.
• ⚠️ Support the glass securely—if it drops, it can shatter and cause injury.
• ⚠️ Wear gloves and safety glasses—door inner panels have sharp edges.
• ⚠️ Keep fingers clear of the regulator scissor/cable path during testing.

📋 Before You Begin

• Park on level ground, shift to Park, and remove the key.
• Lower the window to about halfway if it still moves (this usually exposes the glass-to-regulator fasteners).
• Disconnect the negative battery cable using a 10mm socket.
• Lay a towel over the door sill to protect paint and trim.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the interior door trim panel

• Use a trim removal tool set to gently pry off small trim covers (around the pull handle and switch area).
• Remove screws using a 7mm socket and/or Torx T20/T30 bit (locations vary by door trim).
• Use panel clip pliers or a trim removal tool set to pop the panel clips free around the edges.
• Lift the panel upward to unhook it from the window ledge.
• Disconnect electrical connectors using a pick tool (press the lock tab, then pull). Don’t yank on wires.

Step 2: Remove the water shield (vapor barrier)

• Carefully peel back the water shield using a razor blade or plastic scraper to separate the sticky butyl.
• Set it aside cleanly so you can reuse it (or replace the butyl with new water shield butyl tape).

Step 3: Support and secure the door glass

• Shine a work light into the door and locate the glass-to-regulator clamps/bolts through the access holes.
• If the regulator still moves, temporarily reconnect the switch, reconnect the battery, and “bump” the window to align the fasteners in the access holes. Then disconnect the battery again using a 10mm socket.
• Secure the glass in the fully up position using painter’s tape (2") from the outside of the glass over the door frame.
• If needed, add 2–3 strips of tape for strength. More tape is safer.

Step 4: Detach the glass from the regulator

• Loosen/remove the glass clamp/bolts using a 10mm socket (or the appropriate Torx bit set if equipped).
• Confirm the glass is fully supported by the tape before you let the regulator drop.
• Torque on reassembly: Tighten glass clamp/bolts to factory specification (overtightening can crack the glass).

Step 5: Remove the regulator and motor (bolt-in or rivet-in)

• Unplug the window motor connector using a pick tool.
• If your regulator is bolt-in, remove fasteners with a 10mm socket and ratchet extensions (3" and 6").
• If your regulator is riveted, center-punch the rivet heads using a center punch, then drill them out using a cordless drill with a 1/8" pilot bit followed by a 1/4" drill bit.
• Carefully maneuver the regulator assembly out through the large access opening.
• Torque on reassembly: Tighten regulator/motor mounting bolts to factory specification (use a torque wrench).

Step 6: Transfer the motor (only if your new regulator does not include it)

• Mark the motor position before removal using a marker (if available) to help align it.
• Remove the motor screws using a 10mm socket or Torx bit set (varies by regulator design).
• Install the motor onto the new regulator and snug the fasteners evenly.
• Torque on reassembly: Tighten motor fasteners to factory specification.

Step 7: Install the new regulator

• Position the new regulator inside the door and align mounting holes.
• If riveted style, install new rivets using a rivet gun (specialty) (a rivet gun is a hand tool that squeezes and sets rivets to clamp parts together).
• If bolt-in style, install bolts by hand first, then tighten with a 10mm socket.
• Torque on reassembly: Tighten regulator mounting bolts to factory specification using a torque wrench.
• Reconnect the motor electrical connector until it clicks.

Step 8: Reattach the glass to the regulator

• Remove some slack in the tape so the glass can settle into the regulator clamps.
• Install/tighten the glass clamp/bolts using a 10mm socket.
• Torque on reassembly: Tighten glass clamp/bolts to factory specification.

Step 9: Function test before reassembly

• Reconnect the negative battery cable using a 10mm socket.
• Plug in the window switch and cycle the window up/down while watching inside the door with a work light.
• Listen for popping/clicking and watch for the glass tilting forward/back.
• If movement is rough, loosen the regulator mounting slightly with a 10mm socket, align, then retighten. Small shifts make big changes.
• Disconnect the negative battery cable again using a 10mm socket before reinstalling trim.

Step 10: Reinstall the water shield and door panel

• Press the water shield back onto the door using fresh water shield butyl tape if needed (keep it sealed all the way around).
• Reconnect all electrical connectors.
• Hang the door panel on the top lip, then press clips in around the edges.
• Reinstall screws using a 7mm socket and/or Torx T20/T30 bit.

Step 11: Final test

• Reconnect the negative battery cable using a 10mm socket.
• Cycle the window fully down and fully up several times.
• Confirm the door opens/closes without rubbing and the panel is secure.

✅ After Repair

• Verify the window seals evenly at the top and doesn’t whistle on a road test.
• Confirm the window moves smoothly and doesn’t slow near the top (a sign the glass is misaligned).
• Recheck that the water shield is fully sealed to help prevent water leaks into the cab.
