hello,

this morning the interior fan stopped working all together, have seen a few posts relating to this on the std models, but mines has climate control, so not just the basic 4 speeds.

Is the system the same in principle? a resistor pack somewhere?

any help appreciated
 
Not sure on the fuse without looking it up but that will be in your handbook and will probably be fine. The models with climate control don't have the same resistor as a manual but the fans pack up quite often. Turn your fan on to max get your head in the passenger footwell and give the connection a good riggle. If the fan starts but is really slow you will need a new fan motor
 
Hello,

I have a problem with a fan on my GP sport 1.9JTD too. For a year long now.

First of all I have put ''cable shoes'' (correct expression?) instead of connectors on the electronic resistor and a fan. On all 6 wires - as some people were talking about bad loosing connections and melting connectors, and guessed that problem might be in connectors. So, now it is 100% tight connected with shoes and OK, but I still have problems.

I don't know which one is faulty, fan or electronic resistor with cooler screwed on a fan? Or maybe something third? When I move wires around fan sometimes it stops rotating but I can't say which wire as it is moving pretty much all together, at least a bit........

Another simptom is that the fan is sometimes not working from start of driving so I have to say my passenger to kick gently with a leg around fan.

At summer time I am always using temperature set to ''LO'', with full speed of fan, and sometimes when I think it is blowing OK, after 10min of driving it starts to blow even faster (not a lot faster, but senseable).

So I really have no idea what is joking with me here. Anyone can suggest something? I am guessing that somewhere the power connection is lost, but not outside, I think it can be some loosen soldering inside of the electronic resistor or soldering around terminals for cables.

I am just asking if someone can tell me what to try first, new fan or new resistor, if the problem is common?
 
Sounds like your GP is not auto-AC, right ?
With auto-AC, the fan is controlled by the Automatic AC Controler and is free of those crappy resistors and looms (btw cable shoe is understandable though the correct word would be terminal or even ferule ... ;-)
I've attached the wiring diagram for a manual fan speed selector so you can have a rough idea how it works and what could happen...
As you can see, C016 is a critical earthing point for the fan and recirculation flap motor and needs your personal attention !

Hi,

Fan is controlled by "climate control" with display, so it's automatic.
 
There is no resistor set on automatic climate control, but an "electronic fan variator" (M072 on the drawing) that might be looking like a resistor network with huge lugs (other word for cable shoe ;-).

The more information we receive, the more we can help...

Yes, I am talking about this M087 variator.

And I can't give you more informations. I have just described all the symptoms.

As I know that resistors for manual control were faulty I am asking if maybe this variators are faulty too and if they are dying often in some years, as the car is from 2007.

I am asking if symptoms I said are describing more dying fan or dying variator? What to exchange first?

Hi. Use the excellent GUIDE. to remove the fan. And check for free rotation..

Smell for burning. Etc.

You can power the fan directly from a 12volt source to see if it runs quietly/reliably

Hi there,

my comment about the lack of details wasn't specifically for you but more a general one; people are asking for help, which is basically why the forum is, and that's fine but too often they don't give the very minimal information. Beside presenting yourself so we can call you something different than Gzorlub1357HH it is useful to know what model of car you have (engine/power/version) and trim version...
E.G. for question related to ventilation fan, it's good to know if it's an automatic or manual climate control since some parts are very different...

Regarding your specific case, you're refering to M087, what do you mean ? The electronic variator is M072 and the motor is M085...
M072 receives power from earth and fuse/relay in the junction box (engine bay). This power is modulated by signal received from the Climate Control Unit [A](probably PWM) and outputs to the fan motor [C].

You can by-pass the M072 and power the fan in direct so you can rule out both components...

Maybe you already tried it (read through the posts fairly quick).

I had a problem where the fan suddently stopped, then on/off/on/off constantly at any given fanspeed.
Turned out one of the power cables was faulty. The wires make a loop down and up to the fan I suspect a passenger (maybe me) at some point had accidently hit the loop to many times with the tip of a shoe.
When I wriggled the cableloop I would replicate the error... Is fixed now.

Check the cable loop while you are down below the glove compartment fiddling with the resistor/variator :)
