Ok. I'm a noob to Subies, so bear with me. I thought this at first too, but I think I ruled out the ignition switch. With the fan on, etc, I unplugged the switch from the harness and everything was still running.

I should clarify what stays on/has power while the key is out. Passenger side radiator fan, power windows, blower motor, and some dimly lit warning lights in the instrument cluster.

I actually unplugged these while the fan was running and the fan started blowing even faster. Unplugging those 3 basically just took a load off of the shorted circuit.

Yep, that's why I'm asking here to get some ideas.

Hmm, haven't looked into this. Would the signal/brake light bulbs need to be on in order to create the feedback?

Are these 3 connectors the 3 on the passenger side underneath the air intake, close to the transmission? I haven't done any work to it, but the guy who owned it before me had the head gaskets done about 120 miles ago.

Correct. This is what lead me to believe the problem isn't the relay, as the energizing wire has power even with the key out.

Tested the main relay with the power off. No power coming out. I initially was going to go after the relay, but after thinking about it, with power tested at the light green wire (energizes the relay), I kind of ruled it out. If the relay were stuck, wouldn't the energizing wire have no power?

grossgary, thanks for the info! Yeah, I'm trying to find anything I can to rule out the ECM, but I don't know where else to look. Any ideas? Disconnecting the battery will shut off the fan/accessories, as well as disconnecting the ECM. After cycling the key, the fan/accessories have power even after removing the key. I tried following the main relay and if I read the wiring diagram correctly, there's a light green wire which energizes it. Wiring diagram shows that this light green wire is #63 pin for the ECM which is verified as having power there as well. Any idea of what powers the ECM? Or am I going at it the wrong way?

I've got a problem with my '98 LGT where I'm getting accessory power as well as the radiator fan running all the time. I'm getting this with the key out. Also, I'm getting dimly lit warning lights in the instrument cluster, almost like there's some sort of power feedback. From doing a little bit of testing, unless there's a relay that turns on and shuts off the ECM, I'm looking at a bad computer. Anyone know if Subaru's ECMs are interchangeable between the Legacys or Foresters as long as the basics are the same, 2.5L, AWD, Automatic, etc.?
