How can i fix my Renault Megane 2.0 coupe 1996 windscreen/interior blower u?

i have the same problem on my 2001 megane coupe...a guy from the renault repairs garage said that its common amongst megane coupe's...have u noticed that it isn't as bad wen the car is warm alredy before u start it? i dont know how to repair it though..i think he mentioned something about having to take the whole front panel off from the air filter on the right side to fix it =S
