In the heaterbox?
Probably the bearing....
In any case repair or inspection requires the removal of the glovebox surround and the air intake/fan housing behind it. If you aren't paying somebody to do the work it'd just be a couple or ten bucks for the bearings, provided the motor's good.

Re: EF fan making noise & burning smell?

Riverrrat..
This is a bit long but it may help you..
If the smoke you had out the vents smells like a bushfire, read on..

I’m not sure if there’s any real differences in the fan housing from EA to EF but I had exactly the same ‘leafy’ type noise problem with my EA then smoke through the vents, just like you described.

The problem I had was dry leaf litter (gum leaves) in the fan housing, which eventually started smouldering on the fan resistors.

To fix the problem I took out the fan resistor assembly (which are a set of resistors that are used to select different fan speeds) and found a lot of accumulated leaf litter inside the lower part of the heater housing. (keep reading to find where the resistors are)

The very dry leaves that had accumulated in the fan housing had started to smoulder from the heat of the resistors.
(I’d guess that if there’s a leaf stuck in the fan that causes the noise, it could slow the fan down and the resistors will get hotter on slow speeds.. maybe?)
I found the resistors where ok but it was obvious that the dried leaf litter was scorched and was the cause of the ‘bushfire’ smoke.

Maybe it more likely to happen if you park under a gum tree or travel a lot in the bush? I do both.

I cleaned out what I could through the fan resistor opening (and found one large leaf that was probably causing the noise). Then gave the housing a blast with an airline. Bits of gum leaves and sh*it went everywhere – but better out of the fan housing than in it.

I put it all back together and it’s been ok for about 18 months or so with no ‘leafy’ noises from the fan and no smoke.
No parts needed, no cost at all apart from the time spent cleaning out the accumulated crap in the fan housing.

Now..
Where the hell is the resistor block? I hear you ask..
To find the resistor block, take the glove box out and look around the lower part of the fan housing. You’ll see the wiring connections and a couple or three screws holding it in.
As I said before, EA and EF are probably similar, and hopefully this will it’ll give you some idea of what to look for.

On a different subject..
I had an interesting thermostat problem in the last week or so – but I see there’s a different thread on them such things has come up in the last few days while I’ve been away, so I’ll paste it in that one
