Hi all,

My electric aerial (antenna to you US-ers!) has stopped going up and down,
and is stuck somewhere in the middle. It doesn't seem to be the electrics or
the motor - when I turn off the car I can hear and feel the motor trying to
wind the aerial in, but it doesn't move. I've tried gently pushing/pulling
it and it doesn't want to move, but I don't know whether that's because
something is jammed, or because it wouldn't do that even if it worked
properly. I can twist/turn it to the left and right at its base, so it
doesn't seem to be stuck there, and similarly I can compress each individual
segment of the arial a millimeter or two into the next one, so nothing seems
to be completely jammed up. Any pointers?

thanks

Eric
