Automatic Climate Control maintenance

JARblue

Seen far dirtier filters than the OP's (can still see white on his) with no ill effects other than smell. I've driven cars for 10+ years without ever touching the cabin filter.

That's what Nissan Tech Line also stated in regards to affecting Climate Control functionality but it sure did with mine or Nissan would NOT have tried to replace various electronic modules during their attempt to make mine work as designed. I just know that now it is 100% functioning as it did when I first got the car back in 2016 & can't argue with success directly after replacing the dirty filter. Also, I see there is a bit of white still showing on the outside but the internal slits are really totally blocked at the inner most areas creating very limited air flow.
