You need to change your thermostat in the car.
If a 1988 Lincoln Town Car is blowing both hot and cold air when the air conditioning is on, there could be a problem with the thermostat. There might also be a problem with the level of refrigerant in the air conditioning pump.
if car is blowing cold air, you need to check the thermostat,the heater core, and the heat control. the coolant will not blow cold air unless there is no coolant at all in engine,then you have bigger problem anyway
Low coolant and a clogged heater core are possibilities.
faulty control valve on heater or air in the lines
When the car is off. sounds like a short in the blower or short in the wires
Car not blowing air or heat
Have you checked your thermostat?
because you car is stupid
needs heater core replaced wost likely be hind the glove box
The substance that is blowing out of your air conditioner is likely not smoke, but fog (water vapor). If the surrounding air in the car is met by the cold air blowing from the vents, "fog" is produced. Meineke is a good car air conditioning repair shop.
if its blowing, but not blowing cold its low on coolant. it takes r134a.
