2001 Sonata 4 cyl. heater problem.
We are experiencing a loss of heat after driving 45 minutes. The dealer
can't find the problem. Any similar experiences out there? Any correlation between using the wipers and the heat problem. |

Have you replaced the thermostat? That's the most common cause of heating problems. If your car has an electronic heater control module like the newer cars do, that's also a likely culprit, especially if the heat works initially, then malfunctions. |

Re: 2001 Sonata 4 cyl. heater problem.
Improper coolant level, clogged heater core, thermostat stuck open. Many
possibilities. Has your dealer ever been able to experience the no heat issue? If not, you may need to provide specific instructions as to how they can duplicate. Does it tend to happen to you on a particular stretch of road? What type of driving are you doing when it occurs? Try to give as many details to your dealer as you can. |

The heater cuts out in inclement weather while we are using the
windshield wipers. |

Do you mean that the blower stops or that the air becomes cold?
There's no link between the heat and the wipers, but it's theoretically possible there's an electrical issue affecting the wipers and blower. |

The blower works fine but it blows cold.

Re: 2001 Sonata 4 cyl. heater problem.
I'm pretty much at a loss. There's just about zero connection between the
wipers and heat. It would seem that if the dealer can make it happen, they should be able to figure it out while it's happening. Sorry I don't have more to offer. |

If it's blowing cold air, it would seem that it would have to be a problem with the heater control module. Perhaps it's not be reading the setting on the temp dial and consequently it's not opening the valve on the heater core. I don't know how that would be related to the wipers other than they're both electrical issues. |

I haven't yet seen a schematic for a Hyundai, but my Chryco minivans have several common ground points where several circuits come to a common ground. If one of these connections gets corroded between the wire terminals and the chassis or comes loose from the chassis, one circuit will be trying to use the other circuit as the ground path. This can cause seemingly unrelated circuits to "crosstalk" and have weird things happen. Maybe Hyunday doesn't use such a wiring architecture, but it almost sounds like this. Matt |

If you've got the auto controls, what Brian describes is possible. If
they're manual, I believe the heater door is vacuum operated. |

From what I understand, the '01 and up Elantras all have electronic controls, although they changed somewhat in '04. |

Re: 2001 Sonata 4 cyl. heater problem.
I'm not sure whether they're the same. In fact, you're making me question
whether I was correct on the vacuum operation in my earlier post. The manual climate controls are so trouble-free, I'm not sure if I've ever had one of the newer ones out. I suppose the way to check is to go to the schematics and have a look around. |
