No heat in cabin, fan speed only 2 bars in Auto mode
If it weren't for the issue with the auto mode, I would suspect replacement of the heater core may be necessary. There are no symptoms of a leaking heater core with the exception of the occasional smell of anti-freezed from the vents prior to replacement of the coolant recovery tank. Any help would be great as it is cold in Colorado now. Thanks! |

Does the fan motor itself run??? (You just talk about 2 bars on the display- no discussion of the actual motion of air..)
There may be some stuff you can look at with a proper BMW codereader tool.... IHKA is the heater control as I recall, maybe a reset?!? |

No heat in cabin, fan speed only 2 bars in Auto mode
The fan functions properly on the manual settings from lowest to highest. Even when using the manual settings, there's no heat. The code reader didn't give any fault codes related to heating/AC, so I'm really stumped on this one.

what code reader? Just an OBD reader? You want something that can interrogate the climate system and reset it some interesting reading on similar systems...https://www.northamericanmotoring.co...e-problem.html |

Thanks for the lead. I reset the climate system and all is working as it should. Cabin temperature heated to 82 degrees, auto fan working as it should be for Soft, Medium and Intensive settings!

Was the reset you performed the diagnostic mentioned in the linked thread above?

I reset it using a Foxwell NT510 scanner. I attempted the procedure in the link, but failed. Luckily the Foxwell has reset functionality.

Nice.
Yes, the foxwell lets you access IHKA functions. |

Ahh, I thought it was a button smashing thing. I'll look into the Foxwell.
