What's wrong with my Santa Fe's heater?

Hi, the blower on my 2005 Hyundai Santa Fe works fine when on face/floor mode, but when I turn it on to window no air or very little air blows out. I have replaced the cabin filter thinking that would work, but no joy. Any help would be appreciated.

Hi James,

This is a difficult one to diagnose from afar. There's either something wrong with the control and its signal to the ventilation system or with the actuator that diverts air to the windows. Have you confirmed that air does blow out as fast as ever via the face/feet vents when in those modes?

I'm afraid we'd have to recommend bringing the car at the very least to a good mechanic, but probably best to a Hyundai service centre as it's more likely they'll have seen it before.

If you are hoping to tackle it for yourself, you can start by removing the glovebox, which is relatively easy. The unit sitsbehind that. Just don't expect it to be easy to work on...

In the meantime I'll contact a Hyundai service technician and will let you know if we can tell you any more.

Best of luck.
