You should focus more on the speed controller of the fan.
Astra H - Location of Climate Control ECU
My interior blower fan is not working.
It's not the actual fan, it moves freely, and work given 12v direct.
I tried to diagnose problem with Opcom, and it mentioned Climate Control ECU failure.
I thought maybe the ECU may be part of the three dials switch unit, but nope, after trying two of those.
Where is it ?
Any ideas ?
Thanks

Then i've replaced it (heater blower resistor) ... with no joy...
Thanks
What else then, there is nothing else between climate control panel and this controller. Maybe a blown fuse.
Just an update to this - I believe its fixed.
The heater blower resistor that I replaced in the first place was duff. Bought a new one and its all working again.
I was going round in circles as you don't expect a new part to be broken, lessons learned though.
Thanks all for reading and I hope this helps others.
That resistor should be at least 128c some of them below that value, melting off oftenJust an update to this - I believe its fixed.
