Q: How to check and replace the antenna and cable assembly on a Mercury Cougar?
A: With the antenna cable installed on the vehicle and the cable unplugged from the radio, check the antenna with an ohmmeter at the points shown in the accompanying illustration (Antenna resistance check). If any readings are not as specified, replace the antenna and cable assembly. Disconnect the negative battery cable. For a power antenna, lower the antenna, remove the rear screws from the right side front splash shield for access and remove the lower antenna bolt. Remove the nut at the top of the antenna stanchion and remove the antenna through the fender opening. Installation is the reverse of removal. For a manual antenna, detach the holding straps from the instrument panel and lower the glove compartment. Remove the screws and detach the right cowl side trim panel. Unplug the cable from the radio. Disengage the antenna cable from the clips and retainers along the top of the heater/air conditioning assembly. Remove the radio antenna base cap, remove the mounting screws, pull the base and cable assembly out through the holes in the door hinge pillar and remove the assembly from the vehicle. Installation is the reverse of removal.
