VN- Cooling Fan not working

[VNracer]

Hey i own a VN and my fan isn't working (when i put the AC on aswell).
The car gets hot when stationary at traffic lights. I've checked the fuses. Wasn"t sure on what else to check or to whether to take it to an auto electrician?
Any ideas would be great

[holden007]

check wiring and connection, but apart from that looks like the fans dead.

[VNracer]

OKay, i will check the wiring furthermore tonight.

So i'd probly be best off buying a fan from the auto wreckers and putting that in? Any clue on how much it would be?

By the fan being "dead" do you mean the fan motor must have a problem.
Cheers

the 2 wires to the motor of the fan, connect them upto the battery and see if the fan runs.
or if your car has air con turn it on and see if it turns on

[VNracer]

OKay, i will have a try tonight.

Yer the fan doesn't work when you have the aircon on.
(i get pretty much no air flow through my air vents even when its turned up to 4.)

Mostly the overheating im worried about but.

Do you just use a standard jumper cable from the batery to the fan?
Would a multimeter be any use? are there any other points to check in the wiring?

Perhaps you should clarify which fan you are talking about. It seems to me you guys are talking about 2 different fans. Thermo fan: the one on your radiator, Blower fan: the one under the dash that operates with your aircon.

[VNracer]

Its the thermo fan.

On a similar vein, I have a VX II Executive, and if I put the fan on level 4 (with the AC on) after about 5 minutes the fan shuts down. If I leave it it switches back on in a few minutes, and runs for another 5 minutes, then shuts down again, etc.
If I switch back to level 3, it starts almost immediately, and runs continiously.
It is very annoying as I only put it on 4 when it is very hot, and I need the AC on.
Any ideas?

hey vnracer, did you get any result on the engine fan? mine quit yesterday on the way back from margaret river. Wouldn't cut in at all, not even with the AC turned on so i opened the little black box in front of the washer bottle up, swapped the fan relay with the horn relay and she's all fixed! (had to use finger instead of horn the rest of the way home ;-)

[VNracer]

No i didn't get any result yet.
I havn't had time to have a good look or its been too hot to get under the hood and have a poke around.
I've already tried changing the fan relay with the horn relay for no result.
Im mite try wiring up a switch to the fan and see if I can get it working. (Started another thread to get some advice on that)
I'll keep you's posted on what happens,
any other advice would be great.

Its been my experience that the reason so many commodores overheat, appart from the cracked plastic radiators, is that the temp sensor fails. The fan is usually OK.

the cheapest and simplest fix is to use one of the adjustable temp sensors that you insert into the top radiator hose and wire it up to trip a relay connected to the original fan. Its useless trying to wire the Holden fan directly thru a switch the current draw on start up is enormous and most switches will just melt.

Any of the popular car parts chains will be able to supply a complete kit of parts, even with detailed instructions.

if it isnt the fan it could be the computer, i had a simular problem a few years ago, the fan stop working. i tried the fan on another car and it worked and a tried a different fan in my car and had the same result. i changed the computer and the fan started working and hasnt stopped since

[gasman]

chek the temp sensor going 2 the moter its a common fault replace it but 1st chek fan is ok
