Hi, Im Caz.

I have a 2002 Honda Accord EX..
The car started making a noticeable humming noise during my morning commute.
I thought it may be the radio, but in fact it makes the noise as soon as the key is in the engaged position in the ignition.
I really REALLY need to get a new car... But I need this one to work for now.. Has anyone had this problem? I dont know really much about cars...
REALLY need some help please guys
