Electrical problem
1990 Oldsmobile Delta 88 6 cyl Front Wheel Drive Automatic

I have a 90 olds delta 88 and the blower motor will not shut off even with the key off. Have traced the wire from the motor to something on the fire wall. what ever this is on the fire wall also has a red wire that also plugs into it. If I disconnect the red wire the fan will shut of. I need to know what this electrical connection is on the fire wall and if the red wire is to be hot all the time. I have even disconnected the dash climate control and the fan still runs. Any ideas. I ;have also removed the relay behind the glove box with no change.
