This procedure covers the removal and replacement of the front window motor and regulator assembly on a 2014 Ram 2500 with 6.7L Cummins Diesel engine.

Warnings

Tools required

Parts

• Window regulator and motor assembly × 1 — Use OEM specification or quality aftermarket
• Door trim panel clips × 1 — Replace any broken clips
• Vapor barrier tape × 1 — If damaged during removal

Preparation

1. Park vehicle on level surface and ensure ignition is off
2. Disconnect negative battery terminal and wait 2 minutes for airbag system to discharge
3. Roll window to approximately halfway position if motor is still functional
4. Gather all necessary tools and replacement parts

Procedure

1. 1

   Remove door trim panel
   Remove the door pull handle cover by prying carefully with trim tool. Remove two T30 Torx screws behind handle. Remove power window switch assembly by prying upward and disconnect electrical connector. Remove all perimeter fasteners securing door trim panel using trim removal tools. Lift panel upward to disengage from door frame and set aside.
2. 2

   Remove vapor barrier
   Carefully peel back the plastic vapor barrier starting from bottom corner. Only remove enough to access window motor and regulator mounting bolts. If barrier tears, it must be replaced or properly sealed with vapor barrier tape during reassembly.
3. 3

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door. Press the connector release tab and disconnect the harness from the motor. Route the connector away from the work area.
4. 4

   Secure window glass
   Raise the window glass to the full up position. Use masking tape to secure the glass to the door frame from the outside, preventing it from falling when disconnected from the regulator. Apply at least three strips of tape across the top of the glass.
   ⚠Ensure glass is firmly secured before proceeding to prevent damage or injury from falling glass
5. 5

   Disconnect glass from regulator
   Locate the two bolts securing the window glass to the regulator lift channels inside the door. These are typically 10mm bolts accessible through access holes in the inner door panel. Remove both bolts and carefully slide the glass upward out of the regulator channels while supporting it from outside.
6. 6

   Remove regulator mounting bolts
   Remove all regulator assembly mounting bolts from the inner door panel. There are typically six mounting bolts of varying lengths securing the regulator and motor assembly. Note the location of each bolt as they may be different sizes.

   Module Mounting Bolts8 Nm (6 lb-ft)
7. 7

   Remove regulator and motor assembly
   Carefully manipulate the regulator assembly through the large access hole in the inner door panel. The assembly may need to be rotated and angled to clear the door structure. Remove the complete assembly from the door.
8. 8

   Install new regulator and motor assembly
   Position the new window regulator and motor assembly through the access hole in the inner door panel. Align all mounting holes with the door panel. Install all mounting bolts finger-tight first, then torque to specification in a cross pattern to ensure even mounting pressure.

9. 9

   Reconnect window glass to regulator
   Remove tape securing window glass. Lower glass carefully into regulator lift channels. Align glass mounting holes with regulator attachment points. Install and tighten both glass-to-regulator bolts securely.
10. 10

    Connect electrical and test operation
    Reconnect the window motor electrical connector. Temporarily reconnect the battery negative terminal. Test window operation through full up and down cycles several times to verify smooth operation and proper alignment. Disconnect battery again before final reassembly.

11. 11

    Reinstall vapor barrier and door panel
    Press vapor barrier firmly back into place, ensuring complete seal around all edges. Replace any torn sections with new vapor barrier tape. Reconnect door panel electrical connectors. Position door trim panel and engage upper clips into door frame. Install all perimeter fasteners and interior hardware. Reconnect battery terminal.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify vapor barrier is completely sealed to prevent water intrusion and wind noise
3. Check that all door panel clips are properly engaged before testing

Verification

• Test window operation through multiple full cycles from both driver and individual door switches
• Verify window closes flush with door frame and weatherstripping at full up position
• Check for smooth operation without binding, unusual noises, or hesitation throughout travel
• Confirm auto-up and auto-down functions work properly if equipped
• Test window express up/down feature and anti-pinch safety system
• Check for proper door panel fit and all trim pieces secure
