The blower resistor in the blower housing for the a/c blower most likely has gone bad and open circuit in resistor. Replace the blower resistor. The smell of coolant in the dash vents may be from a leak in the heater core. It may still be a small leak that may not show up in a leak test or even cause the coolant to get very low except over a long period of time. Have the cooling system pressure tested and a mechanic like one from YourMechanic can determine if heater core is leaking and replace the blower resistor for you.
