What does this wire go to?
 

I'm looking to get the interior fan to work and I think this has something to do w/ it not working, can anyone identify this and tell me where it goes?

Take the gray(?) plastic cover off that's just below the glove box, then you should be able to see where the connection for the fan is. If I remember correctly, mine has a plastic plug with 2 blue wires plugged into it. You definately need to check that wire to see if it has power before you do anything else. Kinda looks (to me at least) like it may have been at one time a power wire to an aftermarket stereo or amp..
