It’s a ’97 540i. The IHKA “Auto” seems not to work; just a whisper of heat, and blower does not run. I can control the blower speed at the panel, and heat comes out, so I assume that the FSU is OK.

The outside temp reading is correct.

Any opinions that the IHKA control panel is faulty? I have not read a symptom like this.

Have not yet done that. Thanks for the link.

I have never read about this symptom, so I decided to throw it against to wall to see if it stuck before I rip it apart.

The guy in the video must have long-haired cats!
