2002 Sante Fe heater/AC problem
My Sante Fe has been the best car I have ever owned. I have 138K miles
and the only issues I have had have been minor. My current heater/AC problem is intermittent but often the fan does not blow any air. I can change fan speeds, hear the fan speed faster or slower but no air flows. Could it be related to the defrost setting? It will work for 5-30 minutes, then stop working, then start working again. Same with the A/C. My other issue (unrelated to the heater/AC) is I hear a "whoop" sound intermittently but I can not repeat it intentionally. I can not tell where it is coming from since it is always just a very short sound. |

It'd be very odd for the blower to operate but not move any air. This
implies some sort of blockage to the air passage. I'll presume you don't have all the air registers shut. |

Re: 2002 Sante Fe heater/AC problem
Correct, the air registers are open. Air will blow for awhile, then
stop for 10 minutes to many hours. Sometimes I will shut it off for 20 minutes and when I restart it might work, might not. I'm trying to find a pattern but have not been successful yet. Closest I can tell it may be related to if the defroster (A/C) is running or just the heater. It seems that something may be freezing over and not allowing an internal door to open -- is that possible? Is there a sensor that might be causing this ? |

Re: 2002 Sante Fe heater/AC problem
That's certainly a possibility. If the evaporator freezes over, the air
won't be able to flow through it. There's a thermostat in the evaporator that is intended to shut off the a/c compressor when the evaporator temperature gets too low. |
