cooling fans wouldnt come on today...?
(yes, i tried searching 1st...to no avail...)
after my first rally-x run today i left the car momentarily with engine running (3 mins max) and got back in to park the car, when i got in, the temp gauge was waaaay up...never had that happen before...:( coolant boiling out the overflow tank, the whole 9 yards.. parked and ran the heater fan to help...temp cooled down immediately thank god (air temp approx 2 deg c= about 35 deg f) fans werent working...checked for a wire having come loose...nope checked fuses...nope, all good relays...nope, good too fans have ALWAYS worked as subaru intended until today, subsequent runs showed no further high temp issues (less than 2 mins each run with approx 1 hr in between) 15 min drive home was fine too :) so is there any other sensor besides the one above #5 cylinder that needs to be found/checked? obviously, i will be checking that one first, since it is accessible and (hopefully) is the culprit!! is there an easy way to FORCE the fans to come-on? ie: pull the wire off the sensor maybe? or perhaps activate the a/c? (a/c pump condensor etc has been removed since it was all shot anyway...) but by engaging the a/c circuit via the hvac controls, would the system automatically engage engine fans do to the increased load? if all-else fails, i'll just run a wire/relay/ switch to the interior and turn the fans on manually...:) or maybe 2 switches to the individual fans and halve the load on my new circuit(s) :) rob |

Check the A/C fuse located right next to the FWD fuse slot

Agreed. When my fans weren't working, the AC fuse was blown.

AHA!!!
i will check that immediately!!! thanks!!! :D |
So was it the fuse?
I've had non-working fans for a year now at least and all my fuses are fine, though I can't get into the sealed ones. I figure I must have blew the motors with moisture/coolant due to the radiator leaking profusely before I sorted that out. |

Yeah this thread is giving me a place to start but I still have to track things down since I've never messed with the temp sensor before.
I'm not sure if there is any wiring that is subject to road salt, though. I do think the problem coincided with a major coolant leak. |

hi folks!
i just got home from (nearly) 3 months away working...:( turns out the a/c fuse was missing...d'oh !! (my mind is running through the sequence of events when i removed the a/c compressor etc...did i actually REMOVE the fuse to "kill" the a/c circuit??) hmmmmmmmm.... anyhoo...re-installing the fuse fixed the problem immediately of course...! silly me!! :( :( rob |
