This was good, Thank You.

As well, one thing I've been doing as long as I can remember is after you wash your car or it rains, if you turn on the ventilation, bringing outside air into the car and set it on HIGH, you shouldn't get that funky musty smell.

I had learned that the water pools in certain areas and if you wash your car and then let it sit it will get that musty smell.

So I usually will turn on the ventilation on HIGH (not re-circulation) and either let it sit for a moment to air it out or take a quick drive around the block and I've never had that musty smell ever again.

Thanks to all that posted tips on how to change the in cabin filter. My filter was caked and gross. I could not have done this without this thread..
