Default 89 hvac blower problems

This car is factory original with 160,000 miles. The blower motor is not working. I have replaced both the motor and the resistor. When it started having problems, the fan would only work with the key on and engine off. When the engine was started, the fan motor would quit. Now it doesn't work at all. I replaced the fan motor and the resistor and still no power to the fan motor. I figure it has to be the mode selector switch, but I cannot find where to buy one or even the correct term for the switch. Any help or advice is greatly appreciated.

Do a search using Ford YH-445 and you can find the blower motor switch
