Oldsmobile 25515446 Antenna Assembly, Radio

Disconnect the negative battery cable. Remove the panel sound absorber pad and unplug the antenna connections. Tape the rear edge of the fender and door, then remove fender screws. Elevate and secure the vehicle, remove the front wheel, rocker panel screws, splash shield, and upper antenna nut using the right tool. Remove the antenna. To install, position the antenna, loosely set gasket and nut. Tighten using appropriate tools. Reassemble in reverse order, applying silicone grease to connectors. Ensure antenna mast works. Reset radio and clock as needed. From the trunk, remove trim panel, antenna bracket screws, upper antenna nut, and lead-in cable. Reinstall, connect the lead-in, secure with screws, and apply silicone grease. Confirm antenna function and reset devices.

To replace a power antenna, start by lowering the antenna mast fully by turning off the radio or ignition key switch. If the unit has failed with the antenna mast in the 'Up' position, it may be advisable to cut off the mast portion to make replacement easier. Next, disconnect the negative battery cable. Access to the power antenna motor is through the inner fender panel, so raise the vehicle and remove the front tire if necessary for better access. Remove the fender skirt attaching screws and pull the splash shield forward to gain access to the antenna connections, using a piece of 2 x 4 lumber as a spacer to keep the shield pulled away. Remove the escutcheon nut and spacer at the fender, then disconnect the electrical leads and remove the antenna and motor assembly through the fender skirt opening. When installing a new unit, make sure the mast is fully retracted and the lower bracket is securely attached to the body.
