Warnings

Tools required

Parts

• Door glass × 1 — Use OEM specification
• Door panel clips × 1 — Replace any broken clips
• Glass run channel weatherstrip × 1 — Use OEM specification if damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Lower the door window completely using the window crank
3. Disconnect negative battery terminal to disable any door-mounted accessories
4. Protect door sill area with shop towels to prevent scratching

Procedure

1. 1

   Remove door trim panel
   NOTE: The 1992 Dodge Viper RT/10 roadster is not equipped with conventional roll-up door glass or window crank handles; it uses removable side curtains. Verify the actual window configuration before proceeding, as this procedure may not apply to this vehicle. Pry the trim bezel around the door latch handle. Locate and remove fasteners around the perimeter of the door panel (typically Torx screws behind decorative caps or along the bottom edge). Once fasteners are removed, use panel removal tools to disengage the retaining clips around the panel perimeter. Lift the panel upward to clear the door latch linkage, then remove from door.
2. 2

   Remove moisture barrier
   Carefully peel back the plastic moisture barrier sheet from the door frame. Work slowly to avoid tearing, as it may be reused if undamaged. If the barrier is adhesive-backed, consider using a heat gun on low setting to soften the adhesive. Set barrier aside in a clean area.
3. 3

   Disconnect window regulator from glass
   Raise the glass manually to a mid-position where the regulator attachment points are accessible through the door service holes. The regulator attaches to the glass channel with 2 bolts. Support the glass from above with one hand or tape it to the door frame in the raised position. Remove the 2 regulator-to-glass channel mounting bolts.
4. 4

   Remove glass run channels
   The glass run channels (vertical weatherstrip guides) are located at the front and rear edges of the door frame. Remove any fasteners securing the channels to the door frame (typically clips or small Torx screws at the top and bottom). Pull the channels upward and out of the door frame to clear the path for glass removal.
5. 5

   Extract door glass
   With the glass supported and disconnected from the regulator, tilt the glass forward (toward the front of the vehicle) at the bottom while lifting upward. Angle the glass through the door frame opening at the top of the door. Guide the glass carefully to avoid contact with painted surfaces or the door frame. Remove glass from vehicle and set on a padded surface.
6. 6

   Inspect regulator and channels
   With glass removed, inspect the window regulator mechanism for damage, wear, or binding. Check the regulator track for debris or corrosion. Inspect glass run channels and door seals for tears or deterioration. Clean the regulator track and door cavity of any debris or broken glass fragments.
7. 7

   Prepare new glass for installation
   Compare new glass to old glass to verify correct part. Check that glass channel mounting brackets are properly positioned on the new glass. If glass run channels were damaged during removal, install new weatherstripping onto the channels before proceeding.
8. 8

   Install glass into door frame
   Tilt the new glass forward at the bottom and guide it downward through the top opening of the door frame. Angle the glass to clear the door frame opening, then straighten it to vertical orientation. Lower the glass down between the inner and outer door panels until the glass channel brackets align with the regulator mounting points.
9. 9

   Install glass run channels
   Insert the front and rear glass run channels into their respective positions in the door frame. Slide channels downward into the door frame guides. Secure channels with their retaining fasteners or clips at the top and bottom positions.
10. 10

    Connect regulator to glass
    Support the glass at the desired height (typically mid-position for access). Align the window regulator arms with the glass channel mounting brackets. Install the 2 regulator-to-glass mounting bolts and tighten to specification. Test the window operation by manually cranking the window up and down through full travel to verify smooth operation and proper alignment.
11. 11

    Reinstall moisture barrier
    Clean the door frame surface where the moisture barrier adheres. Position the barrier over the door cavity, aligning any pre-cut holes for door hardware. Press firmly around the perimeter to ensure a complete seal. If original barrier is torn, install new moisture barrier material with appropriate adhesive.
12. 12

    Reinstall door trim panel
    Position the door panel over the door latch linkage and lower into place. Align the panel clips with their receptacles in the door frame. Press firmly around the perimeter to seat all clips. Install all panel fasteners and tighten to specification. Reinstall the door latch handle bezel and window crank handle with retaining clip.
13. 13

    Final testing
    Reconnect the negative battery terminal. Operate the window through several complete cycles to verify smooth operation. Check for proper sealing at the top of the door frame when window is fully closed. Verify that glass does not bind or make excessive noise during operation. Check door latch operation to ensure trim panel installation did not interfere with linkage.

Reassembly

1. Ensure all door panel clips are fully seated before applying pressure to avoid breaking clips
2. Verify window crank handle is fully secured with retaining clip to prevent handle from coming loose during operation
3. Test window operation before final trim panel installation to avoid rework

Verification

• Window operates smoothly through full up and down travel without binding or unusual noise
• Glass seals properly against weatherstripping when fully closed with no air or water leaks
• Door panel is secure with no rattles or loose fasteners
• Window crank operates with normal effort and does not slip
