antno Posted December 17, 2012 Share Posted December 17, 2012 (edited) Hi I have been trying to work out why my aux fan was coming on before my engine go up to temp? I checked my switch and that was fine so I checked my relay and it operates the exact opposite to the way the workshop manual states. So it puts the fan on when cold and switches it off when hot. So I ordered one from Toyota and it works the same way. It's the right one for my chassis number. Mines a 1996 tt6 with a single aux fan. It may have been changed before. Has anyone had a similar problem or found the manuals to be wrong? Cheers antno Edited December 19, 2012 by antno (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 17, 2012 Share Posted December 17, 2012 Just buy a relay with whatever contacts it needs to work right? Normally open or normally closed, or even one with both types. Few quid on Ebay. Not a problem I have come across. I think you might find the auxiliary fan is also wired up to the air con. Quote Link to comment Share on other sites More sharing options...
antno Posted December 17, 2012 Author Share Posted December 17, 2012 I have removed my air con. Might be something to do with that. It's still odd that it operates opposite to the workshop manual. It is a bit of a shame I spent 57 quid on one and can't send it back. Is there any wiring diagrams about on the forum? Cheers Quote Link to comment Share on other sites More sharing options...
Jurgen-Jm-Imports Posted December 17, 2012 Share Posted December 17, 2012 hi mate, on some ecus you can set the fans to come on before stock settings.. its good for the cars if modded, i got ryan to set mine up this way. Quote Link to comment Share on other sites More sharing options...
antno Posted December 17, 2012 Author Share Posted December 17, 2012 It's coming on when cold and I think it is prolonging my thermostat opening. It is just weird that its a genuine part that is working the opposite way round. I can't remenber it always doing it though. That's what makes me think about the air con. But still just change the point about the workshop manual. I can always make it work but would be nice to leave it the same way Toyota did it.
