Slimline fan wiring

[Mieran]

Got a slimline fan mounted on the rad, its got a blue and black wire.

When connected one way it pulls air through but when connected the other way it just spins and doesn't seem to pull or push :confused:

On the advert it says its a pull/push fan.

What am I doing wrong?

Edit: I want it to push

dont you need to take off the spinning bit and turn it over...

[Mieran]

i don't know

i thought you just swap the wires around

[Iain]

Swapping the wires should change the direction but you'll also be able to remove and rotate the fan blades to "sweep" in a different direction. So a combination of both is what you need I reckon

i got a tx autosport one and i just swapped the wires round

well hang on. It might not be reversable via the wiring; some are, some arent.
So check that first. The other wire maybe an earth so sending a live feed to that is going to damage fan or electrics..
If its not reversable polarity-wise then as mentioned may need fan blades removing and fitting back-to-front or youve just bought the wrong type, need to change it.
If it said push / pull on ad though ; suggests it does reverse
