Hi together I want to clean the climate anage of my Avensis Kombi 4-D4 Bj 07.2004 with a spray (because it stinks). As I read to the instructions for use, there are two procedures. 1.First, the fresh air filter must be removed. -Set outdoor air -Blows highest stage -Spray temperature on cold and then over the fresh air intake. My question: where is this fresh air intake exactly located? 2.Set circulating air -Blows highest stage -Temperature on cold And then spray where d he air is sucked in the most strongly. My questions: where is this place (where the air is sucked in the most strongly) ? -is the removal of filters necessary ? Thank you
