wiper cover

hi all

not got any new parts to play with today :-( so looking for jobs todo lol
just woundering if i remove the plastic cover where the windscreen wipers sit ,is it like on alot of cars that leaves get down there and block the water way bit and stops the heater sucking in air as much?

if so that might explain why i dont get much air ? (as my pollen filter is not blocked)

you should not find big leaves down there buy you may find all sorts down there how to undo it is easy get a very small screw driver and either screw the middle of the retaining plastic plugs or just knock them out and get them when you take the panel off
