I have a Mercedes A205 (C-Class Cabriolet) and I want to apply an A/C cleaner spray through the correct access point near the cabin filter on the passenger side. However, I’m having trouble locating the exact opening where the cleaner should be sprayed into the HVAC intake.
I removed the interior cabin filter, but I can’t clearly see where the spray tube is supposed to go. I’ve taken a few photos of what I’m seeing so far and will include them below.
Any info is appreciated, tips to handle the A/C smell

Be careful with the amount of spray you use. I had a problem on my w211, the fan burned out from the spray fluid.
it seems i was right, the marker on the image leads to the HVAC, i sprayd but not all too much hence i did not have the best result with combating the "gym sock" smell
i also tried the other method as suggested where the filter is placed, but i dont recommend that one, it didnt realy intake and leaked out due to gravity, also it didnt come out under the car compared to the first method
