Ford Repair: Ford JBL Audio System, ford jbl, antenna mast

Question
I have a 1995 Ford Explore (about 80,000 miles)
with a JBL sound system and power antenna.

The power antenna hasn't been fully retracting or expanding for years,
and now the JBL sound system is not operational.

The first thing that I did was
check all the appropriate fuses and relays,
but they seem fine.

Could the problematic antenna have
burned-out another part of the audio system wiring / electronics?

I called the local Ford dealer/service center (Albany CA), and
they told me that they don't have anybody that can fix the audio system.
Maybe I should call them back and
push them to service their car ?

Thanks

Answer
thia is not uncommon, best advise, remove the 9/16 or 5/8 nut holding the antenna in place. turn on the radio and have and assistant pull the antenna out as it extends. then install a new one. you can actually see how this is done on you tube by typing " how to replace my antenna mast on my 199? explorer "
