2009 Mazda Mazda3 fan

The Climate Control meter adjustments to the temperature, and the fan speed meter indicates speed adjustments but the fan never activates. Fan has been tested externally and is functioning.

I think you need to replace this…

This is the blower motor resistor module. I think yours has failed so the blower motor is not getting any power.

Hi Mustangman
Thank you for your attention.
I had already replaced this item.
As of about 10 minutes ago I found the problem to be the Heater Relay which I replaced and the system now functions correctly
My best regards
