🔧 Front Window Regulator - Replacement

Replacing the front window regulator on your Ram means removing the door trim panel, disconnecting the glass from the regulator, and swapping the regulator/motor assembly. This is a common repair when the window is slow, stuck, crooked, or makes grinding noises.

Assumption: This procedure covers one front door at a time. If both front regulators are being replaced, repeat the steps on the other side.

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

⚠️ Safety & Precautions

• Disconnect the negative battery cable before starting. The door contains electrical connectors and a side airbag circuit.
• Keep hands clear of the window glass and regulator tracks. The glass can drop suddenly.
• Support the glass with tape before removing the regulator bolts.
• Do not turn the ignition on with door connectors unplugged unless needed for testing.
• Use care around the door panel clips; they break easily if pried too hard.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect power

• Use a 10mm socket to disconnect the negative battery cable.
• Wait at least 2 minutes before touching any door connectors.

Step 2: Remove the door trim panel

• Use a trim panel removal tool and Phillips screwdriver to remove the visible screws in the armrest, pull handle, and lower door area.
• Use a flat plastic pry tool to release the door panel clips around the perimeter.
• Lift the panel upward to unhook it from the window ledge.

Step 3: Remove the moisture barrier

• Use a flat plastic pry tool to carefully peel back the moisture barrier.
• Keep the barrier clean for reuse.

Step 4: Secure the glass

• Raise the glass fully by hand if it still moves.
• Use painter’s tape across the top of the door frame to hold the glass in place.
• If the glass is already stuck down, support it before loosening any regulator bolts.

Step 5: Disconnect the glass from the regulator

• Use a 10mm socket or 8mm socket to remove the glass-to-regulator clamp bolts through the access holes.
• Carefully separate the glass from the regulator track.
• Move the glass fully up and tape it securely if needed.

Step 6: Remove the regulator assembly

• Use a 10mm socket and 1/4-inch extension to remove the regulator mounting bolts.
• Disconnect the window motor electrical connector.
• Angle the regulator out through the large service opening in the door.

Step 7: Install the new regulator

• Use a 10mm socket to position and install the new regulator into the door.
• Install the mounting bolts finger-tight first.
• Torque to 8 Nm (71 in-lbs) unless your replacement regulator instructions specify otherwise.
• Reconnect the window motor connector.

Step 8: Reattach the glass

• Lower the taped glass carefully into the regulator clamp.
• Use a 10mm socket to install and tighten the glass clamp bolts.
• Torque to 5 Nm (44 in-lbs).
• Remove the painter’s tape only after the glass is secured.

Step 9: Test the window before reassembly

• Reconnect the negative battery cable with a 10mm socket.
• Turn the ignition on and test the window up and down.
• Make sure the glass moves straight and seals correctly at the top.
• If the one-touch feature acts strange, cycle the window fully down and fully up several times.

Step 10: Reassemble the door
