Noisy heater fan.

I got in the car today and started it up, the fan sounds as if it's making a 'swishing' noise. It changes the volume with the speeds 1-4. Doesn't sound like a leaf flapping about type noise. Where would be best to start looking? Something might of come loose after changing the dash and crap got in somewhere?

Really happened overnight, not make a noise until today.

Have you changed the resistor pack for ceramic resistors?

I most certainly have, years ago, to fix the dead speeds / broken wires.

I've seen reports of the ceramic resistors touching the fan.

When I did the heater matrix I did the fan resistors and stripped the fan casing at the same time.
There was all kinds of crap in there causing funny noises.
Worth a fan assembly out and looksee me thinks.

I'd start by taking the fan motor out and having a look at it first?

It can be done without removing anything, you have to lay in some funny positions in the drivers foot well though!

It's located next to the clutch pedal, its black, kind of round with a plug going to it. It is held in by 3 screws, once you have undone them and unplugged it it should come out (you may find pressing the clutch down helps give you more room to get it out )

Once it's out try spinning it by hand and see if it makes a noise, you can also check there is nothing catching on it.

Mine was squeaking and I took it apart & sprayed it with WD40. (Don't tell Pete! )

Mine is now quiet as a mouse and it has been a good 7 months since I did mine.

They were big bulky things, I think that'd be the first thing to check, definitely sounds plausible, cheers!

I'll investigate doing that if I draw a blank with Chris T's suggestion, thanks.

In the end I decided to take the fan out, whoever said it was easy gets neg repped!

Well worst part was getting the top screw back in, I don't think i've ever been in such a bizarre position!

Anyway in the end I think it was a leaf in there, so all is well now! So thanks again guys!
