Window Motor and Regulator - Front

This procedure removes and replaces the front window motor and regulator assembly on a 2008 Dodge Viper, requiring door panel removal and window stabilization.

Warnings

Tools required

Parts

• Window regulator and motor assembly × 1 — Mopar 5037553AA (driver) or 5037552AA (passenger)
• Door panel retaining clips × 1 — Replace any broken clips

Preparation

1. Disconnect the negative battery terminal and wait 2 minutes for system capacitors to discharge
2. Lower the window glass to approximately mid-travel position for easier access to regulator mounting points
3. Have replacement door panel clips ready, as original clips often break during removal

Procedure

1. 1

   Remove door panel trim fasteners
   Remove the door pull handle trim screw cover and remove the T30 Torx screw behind it. Remove the door panel perimeter fasteners using a trim panel tool, working from the bottom edge upward. The panel is secured with approximately 8-10 push-pin style retaining clips around the perimeter. Carefully pry outward at each clip location to release the panel from the door frame.
2. 2

   Disconnect door panel electrical connections
   Disconnect the door lock switch connector, window switch connector, and any additional electrical connectors from the back of the door panel. Press the locking tabs and pull connectors straight out. Lift the door panel up and away from the door to disengage the upper lip from the window sill.
3. 3

   Remove water shield access
   Peel back the plastic water shield membrane carefully to expose the window regulator and motor assembly. The shield is typically adhered with butyl sealant. Peel back only enough to access the regulator mounting bolts and motor electrical connector.
4. 4

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door cavity. Press the locking tab and disconnect the connector from the motor. Secure the connector to prevent it from falling into the door cavity.
5. 5

   Support and secure the window glass
   Carefully raise the window glass to the full up position. Secure the glass in place using masking tape applied from the exterior glass to the door frame, or insert a window support wedge between the glass and door frame. Ensure the glass cannot drop during regulator removal.
6. 6

   Disconnect glass from regulator
   Remove the bolts securing the window glass channel to the regulator lift arms. These are typically 10mm bolts or T30 Torx fasteners accessible through access holes in the door frame. There are 2 attachment points where the regulator arms connect to the glass carrier channel. Once disconnected, verify the glass remains supported and secure.
7. 7

   Remove window regulator mounting fasteners
   Remove the 5 regulator mounting bolts securing the regulator and motor assembly to the door frame. These are 10mm bolts distributed around the regulator mounting plate. Note the position of any spacers or alignment shims that may be present at mounting points.
8. 8

   Extract regulator assembly from door
   Carefully maneuver the window regulator and motor assembly out through the large access opening in the door frame. The regulator may need to be tilted and rotated to clear the door structure. Control the assembly as you remove it to prevent the regulator arms from suddenly extending due to spring tension.
9. 9

   Install new regulator assembly
   Position the new window regulator and motor assembly into the door cavity, maneuvering it through the access opening. Align the regulator mounting holes with the door frame mounting points. Install the 5 mounting bolts finger-tight, ensuring any spacers or shims are in their original positions.
10. 10

    Tighten regulator mounting bolts
    Tighten the 5 regulator mounting bolts in a star pattern to ensure even seating of the assembly against the door frame. Snug the bolts firmly but do not overtighten, as the mounting plate can distort.
11. 11

    Reconnect glass to regulator
    Align the window glass carrier channel with the regulator lift arms. Install the 2 attachment bolts and tighten securely. Verify the glass sits properly in the carrier channel before proceeding.
12. 12

    Connect motor electrical and test operation
    Reconnect the window motor electrical connector. Temporarily reconnect the negative battery terminal and the window switch to test window operation. Cycle the window up and down through full travel to verify smooth operation and proper alignment in the door frame. The glass should rise and lower evenly without binding or tilting. Disconnect the battery again before final reassembly.
13. 13

    Reinstall water shield and door panel
    Press the water shield membrane back into place, ensuring it adheres fully to prevent moisture intrusion. Reconnect all door panel electrical connectors. Position the door panel by engaging the upper lip into the window sill, then press firmly around the perimeter to seat all retaining clips. Install the door pull handle trim screw and cover.

Reassembly

1. Reconnect the negative battery terminal after door panel installation is complete
2. Perform the window auto-up/auto-down initialization procedure if equipped: cycle the window fully down, hold the switch down for 2 seconds, cycle fully up, hold the switch up for 2 seconds
3. Verify all door panel switches and controls function properly

Verification

• Test window operation through multiple full cycles, verifying smooth movement without binding or unusual noise
• Check that the window seals properly at the full up position with no gaps at the weatherstrip
• Verify the window does not tilt or misalign during travel
• Confirm all door panel trim pieces are secure and electrical functions operate correctly
