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.
