2006 STi Gauge turns off when Blower fan is turned on ::fixed::

Corrected the model year.

1. You are correct, this does not help me a great deal, I omly haver the ECU pinout section.

2. Good to know that it is connected to the battery.

3. This is also good.


Re-locate the molex red and see if it makes and difference. In fact you can connect the molex red to the battery. Th ehFS-3 has its internal (=) switch controllered by the red wire of the grey harness.

One thing puzzled me. Can you hear the HFS-3 on-borad relay clicking when this happen?

Thanks for changing the title.

I'll try running the Molex red wire directly to the battery tomorrow.

The problem I'm facing currently is that I can no longer get the blower motor to work. So I can't initiate the problem anymore. With the fan off, the HSF-3 works flawlessly.

However, before I managed the break the blower fan, yes, you could hear and feel a relay clicking on the board.

Richard, get some sleep. And thanks for all the help!
