Low speed fan fault? - JTaylor2005 - 09-05-2016
Alright guys. I am having problems with the low speed fan. If I am sat for a while or after a hard drive and then I stop for a bit the temp spikes but no fans kick in :/ is this most likely the relays or fuses etc? Both fans work fine at full speed when I unplug the temp sensor.
RE: Low speed fan fault? - BiG K - 09-05-2016
Remove the front grill, in a triangular box, there's a bunch of relays. iirc, some of these control the fans and could be corroded.
There's also a loom fault, underneath the front bumper, water gets into the loom connection and corrodes.
RE: Low speed fan fault? - toseland - 09-05-2016
it might seem like a silly question but do the fans come on at all?
pull the temp sensor and see if the engine goes into emergency mode and throws the fans on
RE: Low speed fan fault? - Jonny81191 - 09-05-2016
Iirc he's already checked and they do come on at full speed
RE: Low speed fan fault? - cully - 09-05-2016
as big K says check relays and loom plug on the fan cowl
RE: Low speed fan fault? - toseland - 09-05-2016
I missed that bit lol, quick read during a lesson (naughty me)
RE: Low speed fan fault? - JTaylor2005 - 09-05-2016
Haha rebel.
Okay will try and have a look. I am struggling to remove the stupid plastic cover bit at the top of the rad. The part that's the same colour as the paint work. I don't really have the right tools to pop the clips out :/
RE: Low speed fan fault? - toseland - 09-05-2016
you don't have a screwdriver?
RE: Low speed fan fault? - Toms306 - 09-05-2016
Lol, even a knife or spoon pops those out! The middle has to come out of the clip first BTW.
RE: Low speed fan fault? - cully - 09-05-2016
if you are lucky you can prise the centre pin out to release the rivet
if you are unlucky you punch the centre pin into the panel releasing the rivet
and if like me get so fecked off with the stupid things you bin them and fit rivnuts so you can bolt the panel back on
RE: Low speed fan fault? - JTaylor2005 - 09-05-2016
Ahhh that type of clip
I just beeb pulling at them thinking they are like the pop out type haha cheers 
will go and have a look now
RE: Low speed fan fault? - Toms306 - 09-05-2016
Or if you're the previous owner of my car you just whack in mismatched wood screws at jaunty angles in the hope of holding it on...
RE: Low speed fan fault? - JTaylor2005 - 09-05-2016
Well so far I have snapped the top of one so looks like I'm gonna be using wood screws as well
lolNone of them lived haha. All the tops just sheered off on them all lol
Still won't come off even with the clips out and the bolt removed
RE: Low speed fan fault? - Toms306 - 09-05-2016
The hockey sticks under the lights might be holding it? Have fun breaking the tabs off those...
RE: Low speed fan fault? - JTaylor2005 - 09-05-2016
Got fed up and washed the car instead haha
RE: Low speed fan fault? - Ruan - 09-05-2016
What temperature is it spiking to?
And by that I do not mean what temperature the dashboard says - I'm talking about what the ECU thinks as that's the temperature that the fans are controlled via.
RE: Low speed fan fault? - JTaylor2005 - 09-05-2016
I have no pp2000 and no idea who has one by me so I can't check.
It's fully bled has a brand new decent thermostat so it must be the gauge that's showing too high I would think
RE: Low speed fan fault? - Ruan - 09-05-2016
As someone else pointed out, 306s are OBD compatible, so a Bluetooth OBD adapter and Torque on your phone and you'd be away.
RE: Low speed fan fault? - JTaylor2005 - 09-05-2016
Sweet. One like this do you reckon?

bummer!
RE: Low speed fan fault? - Toms306 - 10-05-2016
There are loads that work with an elm cable on windows as well. All my car programmes work on win10 except pp2k now.
RE: Low speed fan fault? - Ruan - 10-05-2016
Yeah, they're all ELM327 interfaces - you can probably get a USB one that will work easier with Windows and you'll just need an application which will work with an ELM327 interface. Tom can probably suggest something..
RE: Low speed fan fault? - JTaylor2005 - 10-05-2016
Oh sorry it does work with windows by the looks of it but you will need a laptop with blutooth I suppose mate
RE: Low speed fan fault? - BiG K - 10-05-2016
You don't need those clips for the grill... there's a bolt which holds it on well enough! haha
