Cabin blower blocked?

[PhilBob]

Hi,
My cabin blower fan does not appear to be blowing out much air especially early morning. It doesn't provide much air on any setting (windscreen/cabin/feet). I can hear the fan whirring ok. I'm sure it's got worse recently. Any ideas on what the issue maybe? I'm wondering if the pollen filter could be blocked (maybe with moisture?)

Does it work in recycle mode? (indicates a blockage in the scuttle outside)
if it does not blow in recycle mode it could be a blocked pollen filter (behind/below the glove box)

As above....

I'd start by checking the inlet is free of leaves in the plenham chamber behind the starter battery.

Then remove the cabin filter under the dash and re check.

If the fan is still bad you will have to see inside the blower box and look at the blower motor.

A fan blower resistor failure will stop the fan working on speed 1.2.3. but will work on 4.
