Right i am having a senior moment. I have bought an A/C cleaner to give my aircon a quick clean and intend to put in a new pollen filter as a matter of course. The cleaner states to spray some in the vents and the pollen filter area then it says to spray the rest in the cold air intake.
Now forgive me for being thick here but i presume we are talking of the area that houses the air filter? I was just going to open it up and replace the air filter and spray a shed load of cleaner through as it was drawing in air or shall i just spray it in the ducting whilst the car is running?
