🔧 Challenger - Front Window Regulator Replacement

Replacing the front window regulator on your Challenger means removing the inner door trim panel, supporting the glass, swapping the regulator assembly, then reattaching and re-indexing the window. The exact steps (and the correct torque specs) depend on whether your door uses bolts or factory rivets to hold the regulator.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

Quick questions (so I give the exact OEM-correct steps + torque specs):

• 🧩 Which side are you replacing: driver or passenger?
• 📸 Can you upload a photo of the regulator mounting points inside the door (or tell me if you see large aluminum rivet heads instead of bolts)?

⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before working inside the door (protects against accidental airbag/short circuits).
• ⚠️ Support the window glass securely—glass can drop suddenly when the regulator is detached.
• ⚠️ Keep fingers clear of the scissor/cable mechanism while testing.
• ⚠️ If rivets are used, drilling creates sharp metal and flying debris—use eye protection.

📋 Before You Begin

• Park on level ground, key off, and lower the window to about halfway if it still moves.
• Disconnect the battery: use a 10mm socket to remove the negative terminal and isolate it.
• Have painters tape ready to hold the glass up to the door frame.
• “Regulator” = the mechanism that raises/lowers glass.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the mounting style (bolts vs rivets)

• Remove the sail panel (small triangle trim by the mirror) using a trim panel removal tool set.
• Pop off the door handle trim and switch bezel using a trim panel removal tool set and pick tool.
• Remove any visible screws using a Torx T20 screwdriver or Torx T30 screwdriver.
• Lift the door panel upward to unhook it, then disconnect connectors using a pick tool.
• Peel back the water shield carefully (reuse if possible). If it tears, plan to reseal with water shield butyl sealant.

Step 2: Stop here—torque specs depend on what you see

• If you see large round aluminum heads holding the regulator: it’s a riveted setup (requires drilling + new rivets).
• If you see regular fasteners with hex heads: it’s a bolted setup (straight unbolt/bolt back in).
• Reply with the side (driver/passenger) and whether it’s rivets or bolts (or upload a photo), and I’ll give you the exact remaining steps with the correct Torque to XX Nm (YY ft-lbs) specs for your setup.

✅ After Repair

• Reconnect the battery with a 10mm socket.
• Cycle the window fully down/up and verify smooth travel and proper sealing at the top.
• If auto-up/down acts weird, tell me what it’s doing and I’ll walk you through the correct re-learn for your Challenger.
