Chevrolet 15087886 Antenna,Radio

Remove the steel mast from the antenna base. Raise the car, remove the inner fender clips and escutcheon nut, then take out the antenna base. Check the grommet for damage and replace it if necessary. Slide in the new antenna with its lead, fix the escutcheon nut, and reattach the inner fender parts. Lower the vehicle, tighten mounting bolts, and secure the antenna mast. Seal the cowl attachment point with RTV, attach the new lead-in, reconnect the pigtail, and reassemble the grille and molding.

To remove the antenna mast, use a small open-end wrench to unscrew it, taking care to avoid scratching the body by surrounding the base with masking tape. If the antenna base/cable assembly needs to be replaced, remove the glove compartment and detach the lower rear portion of the inner fender liner. Disconnect the antenna mast cable from the radio cable at the connector under the far right end of the instrument panel and attach a fish wire to the cable. Pass the cable and grommet through the hole in the cowl into the fender opening from inside the inner fender liner. Under the hood, remove the antenna mast base mounting screws and pull out the base and its cable. For installation, attach the new cable to the fish wire and carefully pull it back into the body, following the original cable's routing. If the extension cable needs to be replaced, remove the glove compartment and the passenger's airbag module. Release the cable from the clips along the top of the instrument panel and disconnect it from the radio and antenna base cable. Finally, reverse the removal procedure for installation.

To replace the fixed mast antenna first unbolt the negative terminal of the battery. Wearing a suitable tool, with the tape or rag to protect the finish, remove the mast from the mast base and lift the rear deck lid. First, the passenger side deck lid inner trim panel is removed simply by pulling on the edges of the panel in order to release its clips; the carpet may then be rolled back and the convenience net plastic hooks unscrewed. Move the passenger side edge of the right rear carpet trim panel back, remove the cargo light fixture leads and the antenna coaxial cable from inside the wheel housing. Remove the passenger side tail lamp assembly and disconnect the antenna coaxial cable from the quick disconnect and disconnect the remaining antenna ground lead from the body harness. Take off the nut that locks the braided ground strap to the antenna, the screws fixing the antenna bracket, and, finally, gently extrude the rubber gasket from the wheel well. The antenna assembly can be withdrawn through the tail light fixture aperture in the body rear, with the procedure of installation being exactly the opposite of this. In the case of roof mounted unit, remove the rear window trim panel gently, remove the headliner plastic screws and detach the rear portion of the headliner to view the antenna-base nut which you have to loosen to remove the antenna from the roof exterior. Release the electrical connector and the antenna cable harness connectors, and detach the base and the harness from the roof, while the reversing process is the same as the foregoing. On adaptable units, shed the negative terminal of the battery, unscrew the trim panel of the trunk lid, detach the electrical connectors and the Antenna cable harness connectors, remove the base and the harness of the trunk lid and put the Antenna base harness through the hole while reassembling. For power antenna removal it should be understood that only the mast is accessible for servicing by use of a special socket for the mast retaining nut. Perform the same action as when removing the electrical connector of a fixed mast antenna and vice versa, for installation. The following needs to be done to get to the antenna module: the negative battery terminal need to be disconnected and the door sill plate and pillar trim on the passengers side have to be removed, the audio and coaxial cables have to be disconnected from the module, the screws that attached it to the lock pillar have to be unscrewed and the module needed to be and then it is reversed. The antenna cable consists of two cables: with the rear cable lying down the center of the rear ward, and going up the right C-pillar then passing through to the left front part of the car to join the front wire running up from the radio. If a cable has to be removed, then it is only disconnected at both ends and left in the system during connection of a new one. To get to the rear antenna cable look behind the back seat cushion, right C-pillar, front and rear door sills, front passenger seat, carpeting and right kick panel and then unplug the cable from the antenna module and the front cable before installing the new cable. In order to get to the front antenna cable you will need to remove the right kick panel, glove box and radio After you have done that you will need to disconnect the front antenna cable from the radio and the rear antenna cable and after than you will be able to install the new cable.

When removing a fixed antenna mast, one has to use antenna wrench or the open wrench to unscrew it off the mounting base while installation, it is done in reverse of the above-stated process and must tighten the mast tightly. This is how to operate the power antenna mast: reverse the upper mounting nut, switch on the ignition key and the radio and hand guide the mast into position. After it expands to the maximum, pull it out from the base and do not forget to switch off the radio and the ignition. To install, follow the same process but insert the plastic cable into the horn part of the antenna that is placed at the base and fix in position such that the serrated side faces the motor this leaves the motor to retract the antenna while holding firmly the cable. Tighten the upper mounting nut but do not over torque it. For the power antenna motor remove the antenna cable and electrical connector that is below the dash, pull the grommet through the cowl panel, open the hood and remove the ground strap and the antenna cable retainer accordingly. The antenna base and cable have to be removed as well as the mounting bolts and the antenna assembly has to be disconnected from the fender trim, while installation is carried out inversely. In case of the antenna cable, one needs to take off the radio, and any mounting brackets where available, pull out the antenna cable clip, undo the connector at the firewall and remove the actual cable and this is vice versa for the installation.

To remove the antenna mast, use a small open-end wrench to unscrew it. Take care to avoid scratching the body by surrounding the base with masking tape. If the antenna base/cable assembly needs to be replaced, remove the glove compartment, right door sill plate, right kick panel, and detach the lower rear portion of the inner fender liner. Disconnect the antenna mast cable from the radio cable and attach a fish wire to the end of the cable. Pass the cable and grommet through the hole in the cowl into the fender opening. Then remove the cowl cover and the antenna mast base mounting bolts.

Lower the antenna by turning off the radio or ignition switch. If the mast has failed in the up position and is being replaced, it can be cut off at fender level for easier removal. Disconnect the cable from the negative battery terminal, ensuring to disable the anti-theft feature on models with a Delco Loe II audio system before doing so. Remove the screws that attach the inner fender skirt to the fender. To access the antenna assembly, pull down on the rear of the fender skirt and hold it away from the fender using a block of wood. Remove the escutcheon nut that retains the antenna cable assembly to the fender. Disconnect the electrical leads, then remove the bolts that hold the antenna assembly to the bracket and take out the assembly. For installation, reverse the removal steps, ensuring the mast is fully retracted and the lower bracket is secured by the fender skirt retaining screw.

The antenna on the right front fender is a rigid one and cannot be adjusted either up or downwards. If it gets slightly bent, by use of hand, it can be straightened but if it is heavily bent, it means that it needs replacement. To retract the antenna mast, simply unscrew the antenna for the removal of the mast you need to loosen the retaining nut. With reference to figure 4, normally after the mast has been dismantled, one can un-bolt the antenna body and cable assembly from the fender.

To lower the antenna mast, turn off the radio or ignition key switch. If the mast is stuck in the 'up' position, it may be necessary to cut it off for easier replacement. Disconnect the negative battery cable. Access the power antenna motor through the inner fender panel, and if needed, raise the vehicle and remove the front tire for better access. Remove the fender skirt attaching screws and pull down on the rear edge of the skirt, using a 2x4-inch lumber as a spacer to keep it pulled away. Remove the escutcheon nut at the fender and disconnect the electrical leads. Remove the antenna and motor assembly through the fender skirt opening. When installing a new unit, ensure that the mast is fully retracted and secure the lower bracket attachment with the fender skirt attaching screw.

Disconnect the negative battery cable, ensuring that on models with the Theftlock audio system, the lockout feature is disabled before any procedure that requires battery disconnection. For the standard antenna, use a small wrench to unscrew it from the base and replace it with a new one; to remove the base, utilize snap-ring pliers to take off the base retaining nut. For the power antenna, open the trunk and take off the trim panel, then unscrew the escutcheon from the fender. Unplug the electrical connector, disconnect the ground and relay cables, drain tube, and antenna lead, and then remove the antenna and motor assembly. Installation follows the reverse order of removal.

Use a small open-end wrench to unscrew it, taking care to avoid scratching the body by surrounding the base with masking tape.
