Noisy fan

[AndyC]

On the way home from the Wales drive my fan (as in heater/air con etc) started to make quite a bit of what I can only describe as a high pitched whine. It almost sounds like theres a leaf or some paper caught in it (if that makes sense).

 

Any ideas what its likely to be? And is it easy enough to access so I can check theres nowt there before I run her into the stealer?

 

I'm reckoning its most likely a bearing?

 

tia for any help

[lomoto]

never heard of that fault before Andy , not just a slack fan belt ??

[M13KYF]

don't think their is a belt on the heater fan

[Zedrush]

My cam belt sometimes makes a whine but nothing major just where its dry which happens alot on cars. not aircon fan... you should get that checked out, probably nothing

[M13KYF]

there isn't a cambelt as such

ah didnt read post properly thpought Andy meant Aircon compressor was whining

[Zedrush]

cam belt?? aint that the belt that swivel around the cogs at the front of the engine, thought it was called a cam belt

Nope

I got noisy fans too, but usually opening the window and shouting at them to shut up helps for a while

That's the fan belt you're on about mate. There's no cam belt on the zed. Chain driven apparently.

ancillary drive belt

[AndyC]

Definitely not a belt issue guys.

 

Its sounds like its coming from under the dash, only when you put the fan on (regardless of whether air con on or not) and increases with an increase in fan speed which is why I'm thinking it could be some sort of bearing.

fan is easy to get at............. pull off cover under the dash .... undo a 10mm bolt in the top right hand corner and there it is...............

 

undo the white cover on the fan and wd40 it...!!

Cool, will check that out tonight - thanks Stuey

[stuey]

or.......... spray wd down the fan air intake just below the screen.........wiv the fan on full blast

[AndyC]

Thanks again mate

[Liam's Z]

wd40 will work but normally just a temp fix!!!

[AndyC]

Right, so I'm better off checking that theres nothing caught up in there and if there aint getting into the stealer then?

[Zzzz...]

I have had a A/C noise fan but I can only hear it at high fan speed, and it is a very high frequency noise. I have to have radio off, low vehicle speed (no road noise) , and full fan with 23deg C airflow to screen (100%)

 

Because it is under very unusual conditions I decided to live with it...but it could be the fan bearing or free play on the fan axle which is causing the blades to touch the casing lightly and cause this noise.

wont that just also blast wd40 all round the cabin or windscreen after it been sucked through. Everywhere could be covered in oil
