Center wire where?
Ok, the 'fan resistor' is a common failure item. It is notorious for failing, it can cause the blower to run when everything is "off" and it can cause the blower to NOT run at all, or to vary in speed - etc. I'd just change it and see if that takes care of this. Describing to you how to test it is not worth the effort, as it costs less than $30. So let's do that.

If you get under the dash on the passenger side, you can take the covers off, and dig down into the HVAC area and find the 'resistor' mounted near the blower motor, real easy fix! There is a thread here on how to do it but I can't seem to find it.
The radio not playing brings up more questions:
Does the radio face light up?
Does it display any text or station information?
Do you hear ANY "pop" or other noise in the speakers when you turn it on?
The only thing common to the two is this: If the drains below the windshield clog up, water can back up and flow down in the HVAC cavity, which can compromise the blower motor resistor, it then can flow down to the floor, and flood the sound system amplifier, under the passenger's feet. If this has happened, the fix is easy: You need a new amp and some new wiring, this is an easy fix - just takes money. If this IS the issue, it will be a great time for a sound system upgrade!
