HVAC blower fan stops?

[nostrebor]

While diving with a/c on, the fan stopped.

(I had the fan speed set to the 3rd spot)

 

I looked for info on why, and a how-to fix, but search results are far and few.

 

Yes, the fan did work again, after i turned the fan speed to max.

 

I'm asking for any DIY fix (maybe a new blower motor or blower fan resistor?).

by the picture there is lights on your heater control maybe loose connection

silveradosid, thanks for the comment but I posted that picture to show I have the basic control panel, not the one with "auto temp".

if the fan only works on high speed then i would look at the resistor pack
