Fault you had for the fan,it's can be fixed easily,and I don't recommend fitting an electric fan instead of the original one.
And since u have the A/C off your car,I suggest that you take it off the BSI setting as well,so that the system don't recognize it anymore.

This is what I was wondering how to accomplish - and whether it would be having an effect on the fan operation. The car might be 11 years old, but only 40k and garaged overnight, I would hope the wiring is ok. If you can inform me of the process to remove the A/C from the BSI I would be grateful?
I have tested the relays - which I assume are those behind the little black panel next to the fan itself - slow and fast speed?? This would then lead me to the wiring as you suggest.
Engines I can deal with, but electrics are lost on me outside of a car stereo...

Will keep the forum updated of findings
#20: Re: Coolant / Fan issues - PLEASE HELP :\ Author: SinfulDesignCom, Location: Ashford, KentPosted: Fri Jun 13, 2014 3:38 pm ---- Right, tracked down a dodgy wire after all this, and have now re-wired.
Issue now is that it is STILL not working - however, is this due to the fact that I haven't cleared the faults? Thus clearing them will cure?
As luck would have it, my diag laptop is on the blink. So frustrating
#21: Re: Coolant / Fan issues - PLEASE HELP :\ Author: SinfulDesignCom, Location: Ashford, KentPosted: Sat Jun 14, 2014 5:57 pm ---- UPDATE: Cleared the faults and still the issue.
I have run the car to temperature again and the short circuit fault on the relay comes back. I have found that there is a +ve feed going to what should be the switched negative side of the relay... of about +2.4v.
I assume this feed travels back to the ECU somewhere and it is meant to ground to switch the relay, but I am at a loss on this one. If anyone can help, or at the least tell me what reading they are getting from the fan relay, it would be bloody helpful..
Cheers

#23: Re: Coolant / Fan issues - PLEASE HELP :\ Author: Deano, Posted: Mon Jun 16, 2014 4:44 pm ---- I know on old cars u could put a split pin in the plug and the fan would work all the time can u do it on theses if so which plug is it ? Thank lads info much appreciated don't mean to forum jump but our problem might be the same things cheers lads
#24: Re: Coolant / Fan issues - PLEASE HELP :\ Author: SinfulDesignCom, Location: Ashford, KentPosted: Mon Jun 16, 2014 5:37 pm ---- +ve is shorthand for "positive". You can bridge the pins of the fast speed fan either side of the relay coil, but it is not a good idea. I had planned on modifying the setup anyway as the fan cuts in way too late for track use. Unfortunately, the 206 coolant temp sensor works on resistance so it can pass the readings to the gauge, so you cannot replace it with a simple switch as the gauge wouldn't work. My answer is to put a separate sensor into the top hose with a switch operating at a cooler temperature. That way you don't need to worry about ECUs failing due to air con etc., the fan will just work, and if it fails, you have a very simple circuit to test to diagnose.

Evening,
When i purchased a new one from Peugeot its resistance was 0.8 - 1 ohm, when measuring across the coil.
The broken one i took off had no continuity and therefore infinate resistance.
Regards, Richard.
