You know where it's at, right? It's under the glove box in the very back almost where the firewall is, if your a contortionist you can get under there and look up and unplug that plug and see if it's melted, if it is, I'm 99.9% sure that's your problem. All you have to do is un screw the resistor pack and then clip the wire ties that run from the blower motor and stretch out the wires so that you will have room to work on it. I actually clipped the wires going to the blower motor, so I could take it inside and work on it.
Then I took the plug and clipped the plug end off of it and soldered them to the actual leads in the resistor pack, used the heat shrink tubing to prevent the wires from touching and then put it back together. Give me a minute and I'll find you the write up...
