No heat can be a clogged heater core or a thermostat stuck open. No low speed blower motor is a defective Blower Motor Resistor Pack. I suggest you drain and flush the cooling system with the heater set at hot. Replace the thermostat with the correct temp unit, pour in a 50/50 mix of antifreeze and distilled water, and bleed all air from the system.

The blower motor is under the glove compartment
Under the passenger side dash. It's awkward to get to, but it's there.
Under the hood on the evaporator case.

it is located below the glove box on the passengers side.
