For a  year and a half I've never used the radio because I needed the code.
It's  always been turned off. Last week I was lucky enough to get the code
to my  radio from a previous owner of the van (not the guy I bought it
from). After  applying the code the radio works. However, when I turned the van
off, and  removed the key, the radio continues to play. I emailed the PO to
see if he  may have direct wired the radio but haven't heard back. The radio
is VW but  doesn't fit all the way into the dash (sticks out about a quarter
 inch).

Is this likely to be a bad ignition switch? I'm wondering if  that could
also relate to poor headlights and heater blower  issues.

all vanagon radios do that.  turn it off.
