Parts
- Power antenna motor assembly × 1 — Use OEM specification
- Antenna mast (if damaged) × 1 — Use OEM specification
Preparation
- Park vehicle on level surface and engage parking brake
- Turn ignition to ACC position and turn radio on to fully retract antenna mast, then turn off
- Disconnect negative battery terminal
- Allow antenna motor to cool if vehicle was recently operated with radio on
Procedure
- 1Disconnect battery negative terminalUsing a 10mm socket, loosen the negative battery terminal bolt. Remove the negative cable from the battery post and secure it away from the terminal to prevent accidental contact during the repair.Torque specBattery Terminal Bolts6 Nm (4 lb-ft)
- 2Access antenna motor locationThe power antenna motor is located on the right rear fender area, accessible from inside the cargo bed. On crew cab models, it may be necessary to remove or fold back the rear seat to access the interior fender panel. Remove any cargo bed liner or panels obstructing access to the right rear fender well area.
- 3Remove antenna mastFrom the exterior, carefully unscrew the antenna mast by turning it counterclockwise. The mast should be fully retracted before removal. If it does not unscrew easily, do not force it as the internal nylon cable may be binding. Continue to unscrew slowly while gently pulling upward until the mast and attached nylon cable are completely removed from the motor housing.
- 4Disconnect antenna motor electrical connectorLocate the electrical connector at the base of the antenna motor assembly. Press the connector release tab and carefully pull the connector straight off the motor. Inspect the connector terminals for corrosion or damage. Clean if necessary with electrical contact cleaner.
- 5Remove antenna motor drain tubeLocate the rubber drain tube attached to the bottom of the antenna motor housing. This tube prevents water accumulation in the motor assembly. Carefully pull the drain tube off the motor housing nipple and note its orientation for reinstallation.
- 6Remove antenna motor mounting boltsUsing a 13mm socket with extension, remove the three mounting bolts securing the antenna motor assembly to the fender. Support the motor assembly with one hand while removing the final bolt to prevent it from falling. Carefully lower the motor assembly and guide it through the fender opening, being mindful of the coaxial cable connection.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 7Disconnect coaxial antenna cableAt the base of the removed motor assembly, locate the coaxial cable connection. Unscrew the coaxial cable connector by turning counterclockwise. Inspect the cable end and motor connection point for corrosion or damage. Set the old motor assembly aside.
- 8Prepare new antenna motor assemblyRemove the new antenna motor from packaging and verify it matches the original unit. Check that the motor gear mechanism moves freely by gently rotating the gear teeth. Ensure the new motor includes all necessary gaskets and seals. Apply a light coat of dielectric grease to the coaxial cable threads and electrical connector.
- 9Install new antenna motor assemblyConnect the coaxial cable to the new motor assembly by threading it on clockwise until hand-tight. Do not overtighten. Guide the motor assembly up through the fender opening and align the mounting holes. Install the three mounting bolts finger-tight first, then torque in a cross pattern to ensure even seating of the gasket.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 10Connect drain tube and electrical connectorPush the drain tube firmly onto the motor housing nipple, ensuring it is fully seated and oriented downward for proper drainage. Connect the electrical connector to the motor until it clicks into place. Gently tug the connector to verify it is securely latched.
- 11Install antenna mastFeed the nylon cable from the new antenna mast into the motor housing opening while slowly turning the mast clockwise. The motor gears will automatically grip the nylon cable teeth. Continue threading the mast clockwise while feeding the cable until the mast base is snug against the motor housing. Do not overtighten as this can damage the nylon cable.
- 12Reconnect battery and test operationReconnect the negative battery terminal and torque the terminal bolt to specification. Do not overtighten as this can damage the battery post. Turn the ignition to ACC position and turn the radio on. Observe the antenna extending fully. Turn the radio off and verify the antenna retracts completely. Test multiple times to ensure smooth operation without binding or unusual noise.Torque specBattery Terminal Bolts6 Nm (4 lb-ft)
Reassembly
- Reinstall any cargo bed panels, liners, or interior trim removed during access
- Verify antenna mast is properly seated and does not wobble
- Check that drain tube is not kinked or obstructed
Verification
- Turn radio on and off multiple times to verify antenna extends and retracts fully without binding
- Listen for smooth motor operation without grinding, clicking, or excessive noise
- Verify antenna stops automatically at full extension and full retraction
- Check radio reception quality with antenna fully extended
- Inspect antenna base seal for proper seating and no water intrusion paths
- Verify drain tube is properly positioned and not leaking
