Davalos Posted December 22, 2010 Share Posted December 22, 2010 I have a weird one ... maybe. '90 Loyale wagon 1.8 stick non-turbo. I have an intermittent fan issue. It sometimes works, sometimes doesn't. At first, I kinda thought it was random. It stated last year, towards the end of the winter. I started to notice that every once in awhile, the fan just wouldn't work - not in any speed. Other times, it would. No biggie. Minor inconvenience - end of the winter & all, right? And all summer, I don't really think it worked. I never really noticed one way or another - A/C has never worked, so it's not been even needed. But this Fall, I kinda started to realize that it was going to be an issue. By October, it was getting cold - and after awhile, I started to notice a pattern with the fan, which I THINK might help figure it out. The fan either works or it doesn't. And if I had to take a guess, I'd say it's gotta be heat-related. If the car sits out all night, the fan'll start running within about 10-15 seconds when I start. The fan almost NEVER starts-up right away. It's those juicy few moments of anticipation that makes this so much fun hehe! Once the car is warm, however, that's it - no more fan after that. If I get get up in the morning & go out to start him up, the fan kicks-in, and I'm nice & warm on my way to my destination. But once I turn it off, that's it - probably for the day. Any other time I start the car after that, and nothing. No fan, no heat, and BRRR!! ... no matter how many times I do it during the day, the likelihood is that I'm not getting any fan action. This is I would say 90% accurate on both sides of the equation - 10% of the time, the fan will NOT work in the morning, even when dead-cold, and 10% of the time the fan WILL work after it's warmed-up. Any ideas? THANKS! Link to comment Share on other sites More sharing options...

Loyale 2.7 Turbo Posted December 22, 2010 Share Posted December 22, 2010 Worn Relay issues... This Link could be Helpful to Swap Standard Bosch Relays instead of the Weak Round ones that came Stock: http://www.ultimatesubaru.org/forum/showthread.php?t=90403 Kind Regards.

NorthWet Posted December 22, 2010 Share Posted December 22, 2010 Another possible cause is worn out fan motor. My 90 loyale had its motor's brushes and commutator worn down to dust. The differential on figuring this out would probably be: When the fan is on, is it running normally (output flow and sound), or is it is slow and possibly noisy. Normal running would point to the relay, slow and noisy would point to fan motor. Link to comment Share on other sites More sharing options...
Davalos Posted December 22, 2010 Author Share Posted December 22, 2010 (edited) Loyale 2.7 ... Wow ... that was like trying to take a sip out of a fire hose, hehe! Thanks! I think! Not sure which part of that to start with, but ... wow! Looks like I need to go back to school, hehe! Edited December 22, 2010 by Davalos Link to comment Share on other sites More sharing options...
Davalos Posted December 22, 2010 Author Share Posted December 22, 2010 Northwet - it's the same noise level (normal) in about all speeds. The blower has never been a speed-demon. It either works totally normally, or not at all (and we're talking the fan). ruparts - that's weird that you have just about the same thing, just the opposite. I can't figure out if that's worse than what I have ... I kinda think it is, maybe. hehe! Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted December 22, 2010 Share Posted December 22, 2010 ... I think! Not sure which part of that to start with... I Kindly Suggest you to Start Lookin' at the Realys Themselves... Also Behind the Passenger's side Strut Tower, under the Windshield's base; you'll find a Twin Relay's Setup, that Controls when the AC Compressor and the Condenser fan Engages... if those fail, the Blower fan's Relay will Fail too; so I Kindly Suggest you to check all the Relays. Good Luck! Kind Regards. Link to comment Share on other sites More sharing options...

Ah ok - so they're in series ... got it. That makes a lot more sense - I didn't make the connection that they were all in tandem. Thank you!

NorthWet Posted December 22, 2010 Share Posted December 22, 2010 Northwet - it's the same noise level (normal) in about all speeds. The blower has never been a speed-demon. It either works totally normally, or not at all (and we're talking the fan)... There should be a distinct difference in sound and output between the lowest and highest setting of the fan. 1 and 2 should be almost inaudible, and 4 should be loud enough to hear but not annoying. My experience is that the blower moves lots of air (relative to my non-subes) and that they do a darn good job on 4. Loyale 2.7 Turbo is a good guy, so if your symptoms sound like a relay follow his suggestions. If the blower just doesn't seem up to snuff, it is pretty simple to pull out and check out. (A little more messy and troublesome to get eyes on the brushes and commutator... easier to swap with a known good fan if one is available.)
