Under the grill at the wipers, what filter's that.....as I'm getting bad steamed windows in the rain, it's fine when no ones in it, but as soon as you're in, start and move, they start steaming. The blower on 3 helps a bit but not much

Pollen filter definitely under glove box , looks like it's dirty . Leave ac on to dry out the air . Mk1 pollen filter under the scuttle

Ok...I don't have a/c (05 classic)

Isnt a classic on a 05 plate a mk1 (taxi spec)?

He's posted in mk2 section ?

Sounds to me like he/she has a mk1,maybe the op can confirm/put a picture up of said car?
