🔍Draft — verification in progress. This procedure was built from OLP's spec database on September 13, 2026 and is queued for line-by-line review by Chris Hackleman — master technicians with 20+ years each. That review typically completes within 3 days of generation, and this banner changes to a verified badge the moment it does. Until then, cross-check every torque value and fluid capacity against the factory manual, and stop if anything looks unsafe. If something looks off, report it below — a real person reads every report.
This procedure covers the removal and replacement of the power antenna motor assembly on a 2008 Dodge Viper, including trunk trim access and electrical disconnection.
Warnings
⚠Disconnect the negative battery terminal before beginning electrical work to prevent short circuits.
ℹ️The antenna mast may be extended or retracted; note its position before removal for easier installation.

Preparation
- Park vehicle on level surface and engage parking brake
- Disconnect negative battery terminal and wait 2 minutes for system discharge
- Open trunk and ensure adequate lighting for interior work
- If antenna is extended, turn ignition to ACC position momentarily to retract (before disconnecting battery)
Procedure
- 1Access trunk interior trimOpen the trunk and locate the left rear interior trim panel where the antenna motor is mounted behind the driver-side rear quarter panel. The power antenna motor on the 2008 Viper is accessed from inside the trunk area.
- 2Remove trunk side trim panelUsing trim panel removal tools, carefully pry out the left rear trunk side trim panel. Check for plastic push clips or fasteners securing the panel along its perimeter. Work slowly to avoid breaking clips. The panel should release once all retention points are freed.
- 3Locate power antenna motorWith the trim panel removed, locate the power antenna motor assembly mounted to the inner fender or body structure. The motor is cylindrical with the antenna mast extending upward through the body panel and an electrical connector attached to its base.
- 4Disconnect antenna electrical connectorLocate the electrical connector on the power antenna motor body. Press the release tab and pull the connector straight off the motor. If corrosion is present, spray with electrical contact cleaner before disconnecting.
- 5Disconnect antenna lead cableUnplug the coaxial antenna cable from the base of the power antenna motor. This connection typically uses a push-on or threaded coupling. If threaded, turn counterclockwise by hand to remove.
- 6Remove antenna motor mounting fastenersRemove the mounting bolts securing the antenna motor assembly to the body. These are typically 10mm bolts, with 3 bolts holding the motor bracket to the body structure. Support the antenna motor while removing the final fastener.
- 7Extract antenna motor assemblyCarefully pull the power antenna motor assembly away from the mounting location. Guide the antenna mast through the body opening if necessary. The entire motor, mast, and mounting bracket assembly should come out as one unit.
- 8Install new antenna motorPosition the new power antenna motor assembly into the mounting location, ensuring the antenna mast aligns properly with the body opening. The mounting bracket should seat flush against the body structure.
- 9Install mounting fastenersInstall the 3 mounting bolts and tighten in a cross pattern to ensure even pressure. Tighten securely but do not overtighten, as this may crack the motor housing or mounting bracket.
- 10Reconnect antenna connectionsConnect the coaxial antenna cable to the base of the motor, ensuring it clicks or threads securely. Then connect the electrical harness connector to the motor, pressing firmly until the locking tab engages with an audible click.
- 11Test antenna operationReconnect the negative battery terminal. Turn the ignition to the ACC position and then ON position to test antenna extension. Turn ignition OFF to verify retraction. The motor should operate smoothly without binding or unusual noise.
- 12Reinstall trunk trimPosition the trunk side trim panel back into place. Press firmly at all clip locations to secure. Verify all edges are properly seated and the panel is flush with surrounding trim.
Reassembly
- Ensure all electrical connections are fully seated and locked
- Verify antenna mast extends and retracts fully without obstruction
- Check that trunk trim panel is secure and all clips are engaged
Verification
- Turn ignition to ACC and ON positions multiple times to verify antenna extends smoothly
- Turn ignition OFF to verify antenna retracts fully into the fender
- Check radio reception to confirm proper antenna cable connection
- Inspect trunk interior for proper trim fitment with no gaps or loose panels
