I looked in Rod's but couldn't find anything about it. But I recently
replaced the non-power antenna in my '95 and noticed the power antenna
connector there so they are obviously wired for the option regardless if
it came with the car or not. The only thing that came to mind about
your dilemma is if you have the factory radio or not. If you have an
aftermarket radio it is possible that the lead for the power antenna was
not wired to the new radio harness and that would make it appear to be
'dead.'
