Musty Smell coming from AC
It's HOT here in Arizona and lately there is a musty smell coming from the AC, but not all the time. Since there is no cabin filter to replace I bought a aerosol for $8.99 to kill the odors. I used it per directions ( spray in fresh air vent under the hood at windshield and into vents in the cabin) , but the smell comes back. Looking for suggestions...

I do use the fresh air intake as well, and the musty smell is still there. How would you suggest I physically clean the venting system?

Theres a well below the drivers side cowl. It has three udder type drains. If the drains clogg it can grow mold, slime, and the decaying crap in the well will stink. Check that area for nasty crap and clogged drains:
Clean out the well and see if that helps.

I sprayed pure isopropyl alcohol (rubbing alcohol) directly in the A/C intake. I removed the inlet screen so I could spray more directly. This has eliminated the smell in my car. I used the whole bottle, a pint I think.
