Repairing a 1997 Ford Ranger Heater Fan Control?

I have a 1997 Ford Ranger. There is no air conditioner, just basic heat. Anyway I lost the low and medium fan control. That left me only with high. I replaced the blower motor resistor and pig tail (because it was so rusted) still nothing. I took the blower motor out and jumped it and the blower works fine.

I checked continuity from the new tail and it looks fine, any other ideas what might be wrong? Also, when I first start the truck I here a beeping sound coming from under the glove box this beeps for about 30 seconds then quits. It starts beeping again after about 45 minutes of driving.
