This procedure covers removal and replacement of the front window regulator assembly on a 2005 Dodge Viper, including door panel removal, window securing, and regulator installation.

Warnings

Tools required

Parts

• Front window regulator assembly × 1 — Use OEM specification
• Door panel clips (assorted) × 1 — Replace any broken during removal

Preparation

1. Park vehicle on level surface and engage parking brake
2. Lower the window completely if regulator motor is functional, or position window mid-way if motor has failed
3. Disconnect negative battery terminal to prevent accidental window motor activation
4. Ensure door is fully closed and latched during panel removal to prevent damage

Procedure

1. 1

   Remove door panel fasteners
   Remove the door pull handle bezel by carefully prying it out with a panel removal tool. Remove the fasteners behind the bezel securing the door panel. Check for and remove fasteners along the bottom edge of the door panel and at the rear edge near the door latch. The Viper door panel typically uses a combination of Torx fasteners and clips.
2. 2

   Disconnect electrical connections
   Locate and disconnect the electrical connectors for the power window switch, door lock switch, and any additional features (mirror control if present). Press the locking tabs and pull connectors straight out to avoid bending pins.
3. 3

   Remove door panel
   Starting at the bottom rear corner, use a panel removal tool to release the retaining clips securing the door panel to the door frame. Work around the perimeter, gently pulling outward to disengage each clip. Once all clips are released, lift the panel upward to clear the door latch mechanism, then remove the panel from the door. Set aside on a protected surface.
4. 4

   Remove or peel back moisture barrier
   Carefully peel back the plastic moisture barrier to access the window regulator assembly. If the barrier is adhesive-backed, work slowly to avoid tearing. Preserve the barrier for reinstallation if possible; if the butyl seal is damaged, re-seal with new butyl adhesive on reinstallation.
5. 5

   Secure window glass
   If the window is in the down position, carefully raise it to the fully up position manually by lifting the glass. Use masking tape to secure the window glass to the door frame to prevent it from falling during regulator removal. Tape across the top of the glass and onto the door exterior frame securely.
6. 6

   Disconnect window from regulator
   Locate the attachment points where the window glass connects to the regulator lift mechanism. Remove the fasteners (typically 2 bolts) securing the glass to the regulator lift channel. These are usually accessed through service holes in the door inner structure. Once disconnected, ensure the glass remains taped in the up position.
7. 7

   Disconnect regulator motor electrical connector
   Locate the window regulator motor electrical connector inside the door cavity. Press the locking tab and disconnect the connector from the motor. Ensure the connector is moved clear of the regulator assembly.
8. 8

   Remove window regulator assembly
   Remove the regulator mounting bolts securing the regulator assembly to the door frame. There are typically 4-5 mounting bolts accessible through service holes in the door inner structure. Once all bolts are removed, carefully maneuver the regulator assembly out through the large service opening in the door. The regulator track and motor assembly may need to be angled or rotated to clear the opening.
9. 9

   Install new window regulator
   Position the new regulator assembly into the door cavity, routing it through the service opening. Align the regulator mounting holes with the door frame mounting points. Install and hand-tighten all regulator mounting bolts, then torque to specification. Ensure the regulator track is properly positioned to align with the window glass channel.

    Connect regulator to window glass
    Remove the masking tape securing the window glass. Carefully lower the glass into the door cavity and align the glass attachment points with the regulator lift channel. Install the fasteners securing the glass to the regulator and torque to specification. Verify the glass sits properly in the regulator channel.

11. 11

    Connect regulator motor electrical connector
    Reconnect the electrical connector to the window regulator motor. Ensure the connector locks into place with an audible click. Verify the connector is fully seated.
12. 12

    Test window operation before reassembly
    Temporarily reconnect the negative battery terminal. With the door panel still removed, test the window operation by operating the window switch. Verify smooth operation through full up and down travel. Check for any binding, unusual noise, or misalignment. Disconnect the battery again before continuing.
13. 13

    Reinstall moisture barrier and door panel
    Press the moisture barrier back into place, ensuring it seals completely around the perimeter. Reconnect all electrical connectors (window switch, lock switch, mirror control). Position the door panel over the door latch mechanism and lower it into place. Press firmly around the perimeter to engage all retaining clips. Reinstall all door panel fasteners and tighten snugly by hand (trim fasteners are not a torque-spec item). Install the door pull handle bezel. Install the door pull handle bezel.

Reassembly

1. Reconnect negative battery terminal and torque to specification
2. Perform complete window operation test: verify smooth operation, auto-up/down function if equipped, and proper sealing at full up position
3. Check that all door panel fasteners are secure and the panel fits flush with no gaps or rattles
4. Verify all switches and controls in the door panel function correctly

Verification

• Operate the window through full up and down travel multiple times to confirm smooth operation
• Listen for any unusual noises during window operation (grinding, clicking, or binding)
• Verify the window seals properly against the weatherstrip when fully closed
• Check that the window glass travels vertically without tilting or binding
• Confirm auto-reverse function works if vehicle is equipped with this safety feature
• Ensure door panel is secure with no rattles or loose fasteners
