My 2000 focus has had few problems thus far, but yesterday, after sitting
for about 6-7 hours, it wouldn't start. I first thought it was a battery
problem. I had someone give me a jumpstart and I drove it for about 20
miles. During this ride, the radio would cut off and right back on
everytime I used a turn signal or cut the A/C on or off. When I arrived at
home, I turned the engine off and tried to restart. The car would not
restart and hasn't 24 hours later, even when trying to jumpstart. I still
get the door chime and interior light until I turn the key, then the whole
dash goes crazy, there's clicking under the steering column and then the
interior light and chime stop until I remove the key and they start again.
When I try, unsucessfully to lock or un-lock the doors using the key fob
the dash starts clicking and buzzing.

Hopefully, someone knows a thing or two about this and can help me out.
Thanks!
