idosubaru Posted September 7, 2010 Author Share Posted September 7, 2010 the main fan and subfan fuse in the cabin both have power. next i should test the fan connector? one of the pins should have 12 volts and the other is a switched ground, is that correct? thanks guys!

Now you're getting it! Yes - that is correct. Sounds like you may have a wireing issue between the fan and the fuse. GD Quote Link to comment Share on other sites More sharing options...
idosubaru Posted September 7, 2010 Author Share Posted September 7, 2010 Now you're getting it! Yes - that is correct. Sounds like you may have a wireing issue between the fan and the fuse. GD so power goes directly between the fuse and component part? the relay or sensor (CTS) would both be on the ground side of things? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 7, 2010 Share Posted September 7, 2010 Yes - that is typically how Subaru does it. The AC fan relay and the thermo switch are both able to complete the circuit to ground. This way if one of them fails (internal short to ground) it doesn't blow the fuse - just runs the fan continuously. GD Quote Link to comment Share on other sites More sharing options...
