One main fan not work other fan work.

[Suba_GL_87]

1996 Subaru Outback 2.5L automatic.

 

When the main fan on but other passages aide main fan not work but I did replace used fan main and still not work.

 

But I'm not sure which main fan relay failure..

Please help.

Usually, that fan on the Passenger's side, only comes on, when you switch on the A/C

 

So, please try with Engine running plus A/C running on,

 

and let us know if then, both fans spin.

 

Kind Regards.

Actually I remove the ac compression.

The two fans are a main radiator fan and a sub-fan.  The main fan comes on when the car reaches "xxx" temperature (usually around 85 celsius), while the secondary fan only comes on when the AC is on (specific times for this as well) and when the car exceeds a second set of temperatures (higher than what kicks on the first).

 

There should be two green connectors under your dash.  Plug those together and see if the fans cycle on/off as they are supposed to.

Ok, I already did 2 greens connect and passages side main fan didn't turn on.:.

Check the 20 amp fuse for the sub fan in the dash fuse panel.

Fuse box is low level!
