Ventilation system - airflow problems
With the Sydney weather warming up I have noticed a significant decrease in the volume of air coming through the ventilation system.
I went through the checklist of possible causes:
- foreign body
- damaged vacuum hoses
- mechanical bits fouled by the cables/wiring for the mods that are tucked up under the dash
All Good.
In my checkings I removed the glovebox and discovered the pollen filters above the blower fan. Upon inspection they were completely blocked and not allowing any air to pass through (not in any real volume anyway).
I remember reading in the manual (I actually read it when I bought the car) that these should be replaced from time to time and took no notice, after all they are pollen filters......
Providing that you don't hit them with a high pressure hose they are reusable:
1/2 an hour with a not to stiff brush (1/2 inch wide artist type) to loosen the dirt and gentle rinse under the tap (from the clean side) and presto good as new.
Let them dry before re-installing and your ventilation system airflow will be as good as new.
With summer coming on all of you whose cars have some decent milage on might consider the do it yourself approach or get your dealers to check and replace the filters at your next service.
Oh for the do it yourselfer's, no tools are required. Everything just clips off/out.
Cheers..... Otto

and here I thought your DIY duct swallowed a rat or something!
good work Otto! save yourself that $80 youd be spending at the stealership!
Theres quite a few threads in the DIY section dedicated to replacing the air pollen filter.

Damn Otto, that's another thing to go on the list...............however I must point out that if your tinkering has degenerated to checking pollen filters.........I'd be hiding your credit card cause i reckon you are gong to need a new toy soon to fiddle with . The EDFC old hat already!!! LOL!!
Seriously well done!

Good DIY Otto, I'm sure this is gonna save people a fair bit of cash as well (Mazda have a habit of replacing them almost every service ffs!).
That's not so funny. On my other car I sucked up a few things. The worst was a plastic bag up the intake which ended up costing a lot to fix!
