Funbus, Release the fusebox by turning thumb screw 90 degrees then lift it up off its hinges. Taking care not to over strain the wiring, move the fusebox to the left. Now look to the right you will see the pollen filter cover near the bulkhead. It is secured with 3, 7mm head self tapping screws. Once removed you can slide out the filter. You will need to flex/bend it to remove and re-fit. Hope this helps, regards, Fankle.
