#1: Peugeot 206 1.1 cooling fan Author: balder07, Location: norwayPosted: Thu Apr 12, 2012 8:26 am ---- Fan wont kick in when temp goes over 90 degrees. Checked fan with connecting to batteries and it works.
When engine heats up to about 90 degrees the connection plug into fan gets 14V or 12v if motor is switched off.
But when this is connected to fan again it goes to 0V, measuring the amp to only a few mA and dropping to zero when connected. When disconnecting again it shows 14V.
Does anyone knows why the fan wont start?
#2: Re: Peugeot 206 1.1 cooling fan Author: Deckchair5, Location: Bath UKPosted: Thu Apr 12, 2012 9:29 am ---- To have the voltage there but not enough current to drive the fan shows a poor connection/ high resistance in the circuit and if you're saying niether the low or high speed fan settings are working then I'd check the fuse for integrity or poor contact as the same fuse powers both low and high speed fan relays
Whilst you're there I'd check the fusebox connectors for similar poor contact
If the high speed fan comes on but the low speed doesn't then I'd check the slow speed relay and slow speed resistor circuit
#3: Re: Peugeot 206 1.1 cooling fan Author: balder07, Location: norwayPosted: Fri Apr 13, 2012 3:51 am ---- I have checked and cleaned all of the connection i could see beside the batteri. Though I found the fault when i saw some white powder on the earth screw going on the gearbox. But it did not, fan still not going.
I have only one speed on the fan, the car is 1.1 with no aircondition.
I think the connection goes from the batteri - fuse - fan - one wire teminal switch right side of engine block behind therminal housing - earth through engine block so it has no relay or resistor
I have tried to search for similar problem, but i can only find 1.1 206 with terminal switch on radiator. Even when I look up my car in peugeot servicebox, with cars unique number VF32CHFXF41133095, it say that terminal switch is lokated on radiator. But it does not, it is only a plug with no wire.
Any idea where the foult could be?

#5: Re: Peugeot 206 1.1 cooling fan Author: Deckchair5, Location: Bath UKPosted: Sat Apr 14, 2012 2:20 am ---- Your VFxxxxxxx number shows you should have a simple in radiator on/off thermo switch controlling the fan (as you've found) but you're saying you don't have one these
So if you have a wiring diagram or pics of your set up then post them up
In the meantime you could wire your fan with a manual switch to avoid overheating problems

Turned the fan on via the diag port?

I'm currently investigating the same problem, and have access to several diag machines. One we couldn't hook up because it would only read Bosch 7.4.4 ( mine is apparently 7.2.x) and with those we could hook up - we couldn't find a function to switch on the fan. Is a preplex meant to be able to do this via diag. ?
#8: Re: Peugeot 206 1.1 cooling fan Author: Deckchair5, Location: Bath UKPosted: Sat Apr 14, 2012 3:13 am ---- Balder says he's checked the fan operation by direct battery voltage
It seems to be a year 2000 model, I'm guessing this is an ECU controlled fan with engine temp info fed from the single wire engine temp sensor?

Yes you should be able to. I can do it with dealer as well as multidiag. Normally in actuator tests.
And balder, here is the wiring diagram for your engine and emission levels
#10: Re: Peugeot 206 1.1 cooling fan Author: Deckchair5, Location: Bath UKPosted: Sat Apr 14, 2012 6:16 am ---- Hi Lee
If that's Balder's wiring diagram then that's a normal 2 speed fan set up with hi and low speed relays and low speed resistor. If so then it's going to be relays and resistor connections checking time
#11: Re: Peugeot 206 1.1 cooling fan Author: Lee, Location: EnglandPosted: Sat Apr 14, 2012 6:48 am ---- Used his VIN and build code for the diagram.
Should have really checked the relays and resistors anyway, they always fail on the 206 due to the stupid place they are located, causes water ingest and corrosion
#12: Re: Peugeot 206 1.1 cooling fan Author: Deckchair5, Location: Bath UKPosted: Sat Apr 14, 2012 7:13 am ---- Indeed, it's getting the cooling airflow around that resistor that causes the problem of where to site it as the thing would get pretty hot otherwise but the relays could easily have been positioned elsewhere
Still, Balders is going to be happy to discover he has a 2 speed fan when it's all working
#13: Re: Peugeot 206 1.1 cooling fan Author: balder07, Location: norwayPosted: Sat Apr 14, 2012 9:34 am ---- Wow, 2 speed fan would be great:)
I cant find the relays supposed to be in the front, dont think there are any since I can follow the cables from the fan to engine fuse box with no releys in between.
Have taken some picture, maybe its easier to see what cooling system I use. Since I did not find how to put it in here with the text, I made a blog.
Does anyone know if is the thermal switch that I have beside engine block?
#14: Re: Peugeot 206 1.1 cooling fan Author: Lee, Location: EnglandPosted: Sat Apr 14, 2012 10:33 am ---- You need to take the bumper off to see the relays
#15: Re: Peugeot 206 1.1 cooling fan Author: Edward, Location: In the garagePosted: Sat Apr 14, 2012 11:08 am ---- The relays are behind the front bumper under a cover on the fan housing.
The only switch is in the ECU...it monitors the coolant temperature and at certain levels it switches the cooling fan on via the relays behind the bumper.
