My demister fan isn't working on my VS. I'm guessing the VS has got the same setup.
Is the problem most likely a blown fan motor? If so, where is the demister fan and how do you change it.
Thanks

Does your airconditioner fan work?? If it does they are one in the same and your problem will be the vacuum lines going to your selector switch(face, feet, windscreen selector). You will need to pull the selector switch out and you will find a little manifold with all of the vacuum hoses going to it. You will have to track down and replace the busted one.
Give us a bit more info before you start yanking things out though. It may be something a little simpler. |
What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

the fan system in the vs is exactly the same through vn-vs models

I'll show you the Rick James cell. It's superfreaky!. |

| There will be a fan speed resister under the bonnet. On the vn it is under a plastic cover right up near the windsceen wipers. Not sure but you may have to remove the windscreen wiper arms to get at it. I thought that the fan speed resistor in the vs was a solid state resistor and usually doesn't play up. Anyway when you pull the cover off it should have 2 screws holding it into the air con vent. Remove the plug from the resistor and the resistor from the vent. You should be able to pick one up from the wreckers for around $20. |

I did as you said and found the resistor.... It's an old school looking thing and mine seems to look ok
Is there a way to test the resistor and the coils on it are all intact and it all looks good
If it's not the resistor could it be the fan motor itself???
If it is the fan, how do you change one?
Thanks |

The easiest way would be to go and get the cheapest multimeter you can find(autobarn/supercheap just as accurate as the expensive one's) and check and make sure that there is a circuit through all of the coils. While it is out i would be looking at upgrading it anyway to a solid state resistor. Which just looks like a heat sink instead of those coils.
See how you go with that and I will have a look tomorrow at how to test the fan motor.

| I have just had the same dramas in the last few days. you need to remove the plastic cover under the glove box and you will see the fan motor. unplug the fan motor (not as easy as it sounds) and make sure you have power at the plug. Use a test light or the multi meter you just bought. when you find there is power there, start swearing, cos to change out the blower motor is extremely painful. you must remove the dash board.the complete heater/evaporator box must be removed. quick order i did it in is as follows; remove steering wheel, remove instuments,stereo, centre console,glove box. drop the steering column down and remove all a/c ducting. disconect the heater control rod.remove dash speakers and the demister cover at the wind screen.you should be able to unscrew the dash board. be careful and take some photos/notes of where the wiring harness goes. Once dash is removed, you need to remove heater hoses at the firewall in engine bay. remove the windscreen wiper arms and the flimsy plastic cover hiding the wiper motor. remove your a/c gas. undo the socket head cap screw in the middle of the a/c pipes. lift the pipes out of the way.remove the two heater box mounting screws on the firewall. remove all other mounting srews inside the car. there are some sneaky ones up high. remove the heater core hold in clamp. pull the heater box rearward and then sideways towards the passanger side, removing heater core at the same time. and you can now access the blower fan. three screws to remove it. next mission is to find one. holden dont have them. i can only find 2nd hand but there is no way im putting in an old one. im not doing this again. i am im the process of modifying it with anew type motor and can be removed easily. ill update when im finished. i hope this helps. |

Hi Tamo
Thanks for the details for replacing the fan.
I did speak to a mechanic mate I know and he reckons you don't have to pull the dash out of the car to replace the fan... I'm not sure if he's done it though, so will have a look into it
I'm not sure if I'll be going to the effort of replacing the fan if it's gonna be a weekend job - the fan doesn't really mean a lot to me.
It'd be good to know if it can be done any easier than what's mentioned? Surely Holden haven't made it that hard!!
Thanks |

Hi..... An update to my VS fan problem
I pulled the glovebox out and backing cover for the fan behind it and tried disconnecting the fan's wiring
The wiring clip was brittle and looked like it had overheated, as it was crumbling
After I fiddled around with the wiring, the fan started working - looks like it was a bad connection.
Only problem is that the connection is reasonably loose, as the clip is stuffed, so will properly be under there again sometime. Also I accidently pulled out one of the vacuum hoses which goes onto the fan (I think it controls the recirculating and fresh air mix and now seems to have lost affect)
I did look at what would be required to replace the fan and it DOES seem like a big job - probably would need to pull the dash out to get to the top screws - as mentioned by Tamo
Thanks to all who responded
