Cheers Rob. I did snap one of the retaining clips, but even then it was still stuck solid. Managed to wiggle it out without breaking the other one though, phew

Are the hedgehogs all the same part No.?

Don`t buy new unless you`ve got a fat wallet

I have a fellow OOFer who messaged me that he had one if needed. I've sent him a message and awaiting a reply now. Be glad when I finally get this sorted so I've got heat and demisters again!!

Astra G use same hedgehog if you need to widen your search

Cheers for that mate. Said OOFer is posting one to me today and hopefully get it on Monday!!

Just out of curiosity, how does the hedgehog work?

Its a relatively simple solid state speed controller.

Ok, now I'm really hacked off 

My replacement hedgehog unit arrived yesterday evening, happy days, or so I thought

Went out this morning and plugged the hedgehog in, turned the ignition on, turned the blowers on........NOTHING. Still dead 

Now I originally checked all the fuses mentioned previously - all fine

Gave the blower motor direct power - Spins fine.


Could this be an issue with the CC unit?

Are you sure the hedgehog was alive

[blackviper90210]

I was told it was " as new "

[blackviper90210]

Just curious...... I've only connected the hedgehog loose in the footwell. It doesn't have to be in its proper location to "work" does it?

I am assuming that facelift wiring is the same as pfl, but when mine failed it was the loom between the hedgehog and fan. On my car the wires come out of the hedgehog and into a plug, then from that plug to the fan, it was that plug in the middle that had a duff connection. I ended up making a new loom.

Howdy all, The hedgehog was as new and came from my previous Mig and had been fitted very recently as part of a major and expensive heating overhaul to solve the same problem Dave is having. Had a chat with Dave and am more than happy to refund should it turn out to have died in the post but is there anything else in the heating system this could be chaps, feeling a bit grim as a fellow OOfer is in need of his blowers

The system works by the CC unit giving a variable voltage signal to the fan controller, whose job is to convert that signal into a high current capable variable voltage to the fan (obviously, the CC isn't man enough to drive the fan directly).

So, assuming CC has been reset, either CC not giving signal, signal not getting from CC to fan controller, fan controller fault, power not getting from fan controller to fan, or fan faulty.

Some of these have already been checked - fan, speed controller etc.

If you've recently had the HU out, might be worth checking the plugs and wiring going to back of CC unit.

Cheers for the chat earlier Jon and thank you for your offer or a refund, but as I said to you, before I even look down that route, I want to make sure it's nothing else that may be causing this issue!!

I'll take a look at the loom between the hedgehog and blower next as just been suggested by al brown

Is there 12V going to resistor
