Car not blowing air or heat
must have air in the cooling system
One possibility is that the air conditioning is on. My 2001 Elantra automatically starts the air when the fan setting is put to defrost. I have to remember to turn it off.
could be elctrical not turning on compreesor could just be out of freon
What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
Replace Thermostat
Is it blowing cold air only or not blowing any air at all.
looking for answer
because it is broken
it is a heater. heat. it blows heat. warm air
There could be a number of problems. Dirty ducts or heat exchanger. Wrong speed on the fan, or turning the wrong way. Plugged filters or vents.
what's it doing?
sounds like t stat is programmed wrong, reversing valve coil is bad or reversing valve is stuck.
