Q: How to replace a power antenna for Buick Skylark,Oldsmobile Omega and Pontiac Phoenix?
A: 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.
