Q: How to Maintain and Fix an Antenna on 2000 Dodge Ram 3500?
A: Your first step to service or repair the radio antenna is to separate and disconnect the battery negative cable. Under the instrument panel, on the passenger side, take the coaxial cable connector out of its retainer in the heater-A/C housing and remove the foam, then disconnect the connector by turning the metal halves and never by pulling on the cable. Attach the cord or twine to just one of the connection points on the adapter for future usefulness. Climb above the Powertrain Control Module in the engine bay and unclip the antenna coaxial cable grommet from the dash panel; then bring the cable into the engine compartment. To take down the antenna mast, lift up the sleeve and unscrew it from the antenna, then use an antenna nut wrench (Special Tool C-4816) to take off the antenna cap nut. Pull the antenna adapter out of the fender, move the antenna body and cable assembly out of the fender and take the coaxial cable through the right cowl side reinforcement as you pull the antenna. After pulling the cord or twine out from the antenna body and cable coaxial cable connector, pull out the body and cable. Repeat the unhooking for the instrument panel antenna cable and remember to pull a cord or twine through the connector for installation. Pull the glove box open and reach through to reach the retaining clips for the antenna cable. Unclip it and then take the radio receiver out, then pull the cable through the opening. Release the cord or twine from the connector on the antenna cable and remove the whole cable. First, tie the cord or twine to the new antenna cable connector, put the antenna and its cable into the vehicle and pull the cable's coaxial end into the engine compartment and then into the passenger compartment. Push the grommet into the dash opening, place the antenna through the fender, fit the adapter, tighten the cap nut to 8 Nm and tighten the mast to 3.3 Nm. Attach the coaxial cable connector back under the instrument panel, cover it with foam tape and close it with the retainer clip. At last, reconnect the negative cable to the battery. With the instrument panel antenna cable, attach the new cord to your original one, pull the bundle through into the car, install the radio receiver, secure the cables with the retainer clips and slide back the glove box. First, remove the attached cord from the antenna cable, fit the coaxial cable back under the instrument panel, adhere some foam tape around the cable, ensure it is captured by the retainer clip and snap the battery negative cable in place.
