Here is why we change cabin air filter ...
 

Car in for service, 2006 w/33,000 mile...

Here is the cabin air filter, HVAC system smell a little musty or rotten ?

This is why you need to clean around the hood hinge area/cowl at base of windshield of lawn and tree debris.

thanks for the headup. This is often a negelcted but simple change that affects not only the car's perfromasnce but also the quality of life for passengers

does a 2001 Elantra have that?

i thought I looked and couldn't find it.

My 05 Santa Fe doesn't have 1 and it should ...So i need to get a shop repair book and see how it's fitted and get the filter because this AZ dust can ruin an AC system
