Auxiliary High Blower Speed

When the High blower speed is selected, the auxiliary blower motor switch applies a ground to the auxiliary high speed blower motor relay through the auxiliary blower motor high speed control circuit. When the relay closes its switch, voltage is provided by the battery positive voltage circuit. Voltage is sent directly to the auxiliary blower motor by the auxiliary blower motor supply voltage circuit. The auxiliary blower motor switch and auxiliary blower motor are grounded by the ground circuit.
