Power Window Motor - Rear

This procedure covers the removal and replacement of a rear power window motor on a 2014 Ram 2500 crew cab, including door panel removal, water shield access, and motor replacement.

Warnings

Tools required

Parts

• Rear power window motor assembly × 1 — Use OEM specification
• Door panel retaining clips (if damaged) × 1 — Mopar replacement clips
• Water shield adhesive × 1 — Mopar weather barrier adhesive

Preparation

1. Park vehicle on level surface and engage parking brake
2. Lower the rear window to approximately mid-travel position for access to motor mounting bolts
3. Disconnect negative battery terminal and wait 2 minutes to allow airbag system capacitors to discharge
4. Gather all necessary tools and replacement parts

Procedure

1. 1

   Remove rear door panel
   Remove the door pull/armrest by removing two T30 Torx screws from the bottom. Remove the power window switch bezel by prying carefully from the rear edge and disconnect the electrical connector. Remove all visible T20 Torx screws around the perimeter of the door panel (typically 7-8 screws). Insert trim panel tools around the edges and carefully release all retaining clips by working around the perimeter. Lift the panel upward to disengage the top hooks from the window channel and remove from door.
2. 2

   Document and remove water shield
   Carefully peel back the plastic water shield from the door frame. The shield is held by adhesive and should be removed slowly to avoid tearing. If the shield tears, it must be replaced or repaired with appropriate adhesive. Fold the shield away from the work area or remove completely if necessary to access the window motor.
3. 3

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

   Support the window glass
   Use masking tape to secure the window glass to the door frame in the mid-travel position. This prevents the glass from dropping when the motor is disconnected from the regulator. Ensure the tape is secure and the glass is stable before proceeding.
5. 5

   Remove window motor mounting bolts
   Locate the three window motor mounting bolts (typically 8mm or 10mm heads). These bolts secure the motor to the window regulator assembly. Remove all three bolts and retain them for reinstallation. Note the position and orientation of the motor before removal.

6. 6

   Separate motor from regulator
   Carefully separate the window motor from the regulator drive gear. The motor gear meshes with the regulator sector gear and may require slight rotation to disengage. Once free, maneuver the motor out through the access hole in the door inner panel. Be careful not to damage the regulator or other door components during removal.
7. 7

   Install new window motor
   Position the new window motor near the regulator assembly. Align the motor drive gear with the regulator sector gear, rotating slightly if needed to mesh the teeth properly. Ensure the motor is oriented correctly with mounting holes aligned to the regulator bracket. Carefully position the motor onto the mounting surface.
8. 8

   Install motor mounting bolts
   Install the three motor mounting bolts finger-tight, ensuring the motor is properly seated against the regulator. Tighten the bolts in a star pattern to the specified torque to ensure even clamping force and proper motor alignment.

9. 9

   Connect electrical and test operation
   Reconnect the window motor electrical connector ensuring it clicks into place. Temporarily reconnect the negative battery cable. Test window operation by cycling it up and down multiple times to verify smooth operation and proper engagement with the regulator. Check for unusual noises or binding. Disconnect battery again before proceeding.
10. 10

    Reinstall water shield
    Carefully reposition the water shield over the door inner panel, ensuring all openings align properly with door components. Press firmly around all edges to re-adhere the shield. Apply new adhesive if original adhesion is compromised. Ensure complete coverage to maintain water protection.
11. 11

    Reinstall door panel
    Position the door panel and engage the top hooks into the window channel by lifting upward. Lower the panel into position and align all clip locations. Press firmly around the perimeter to engage all retaining clips, listening for audible clicks. Reinstall all T20 Torx screws around the perimeter. Reconnect the power window switch connector and install the switch bezel. Reinstall the door pull/armrest with the two T30 Torx screws.
12. 12

    Final battery connection and system initialization
    Reconnect the negative battery cable and tighten to specification. Perform the window auto-up/auto-down initialization procedure: fully lower the window, then hold the switch in the up position for 2 seconds after the window is fully closed. This reprograms the anti-pinch feature.

Reassembly

1. Ensure all door panel clips are fully engaged before testing window operation
2. Verify water shield is properly sealed to prevent moisture intrusion
3. Reset radio presets and clock if necessary after battery reconnection

Verification

• Test window operation through multiple complete cycles in both directions
• Verify auto-up and auto-down functions work properly after initialization
• Check for smooth, quiet operation with no binding or unusual noises
• Ensure window seals properly at full up position
• Verify all door panel fasteners are tight and panel is secure with no rattles
• Confirm power window switch functions correctly for both up and down
