Question:
2004 Toyota Avalon miles: 56,000 I came out
to my car today and the antenna was hanging
by the side of the car?... I
don't know what happened but I had to cut
the plastic line that was connecting it to
the car. What do I do now? Do I need the
whole new antenna?
Answer:
Sorry about your antenna. The good news is
that you can change it to a new antenna mast
pretty easily. First undo the top mounting
nut then turn the radio on, the remainder of
the feed will be ejected. Then prepare your
new mast for installation. Turn Radio off to
feed the new mast down. Reattach mounting
nut.

Question:
2001 BMW 325i, miles 45,000. I have a
question, if the antenna motor doesn't make
the mast go up but it is getting power is
the motor bad?, or the something else that
could cause it not to work?
Answer:
If the actuator motor is receiving power
then check the ground for the system.
Sometimes the connection is loose or
corroded. A simple cleaning or tightening
can correct our problem. If ground circuit
is good, replace the antenna unit.
Question:
2004 Chevrolet Astro Van 95,000. I replaced
my antenna with a after market kit. I
thought it looked cool so I put it on. Now
Fm radio works ok but the am radio is all
static ? What is up?
Answer:
Thanks for this question. If the antenna you
installed housing is connecting the metal
body. It grounds itself and becomes
inactive. Use the proper insulators and the
problem should go away.
