I recently bought a used 2002 sunfire gt. Occasionally I have to turn off
the engine, restart it to get the windows to go up, sometimes I need to do
this many times before they go up. I have no problem with the sunroof
though.

Another problem is the radio should shut off when I open the door, it has
done this 4 times so far, 99% of the time I have to manually turn it off.

Any ideas of what is causing either of these things?
