Air Conditioning Humidity/Smell when starting (4 Viewers)

[filer5000]

Yet another questions relating to my air conditioning system in my 2007 100 series LC.

Everytime I start my car or the AC gets turned on, I am hit with a temporary wave of really humid air and musty smell. This goes away after around 15 seconds. It does seem to be getting slightly worse and for slightly longer.

I am wondering if my AC drain is possibly clogged or if somethings wrong with my evaporator. It might also be completely normal.

Guidance is appreciated. Thanks.

I was just reading about a Toyota ac refresher kit a few days ago. It’s a foam you spray into the drain to clean the coil. You’d have to clear out a plugged drain first anyway, so that’s the first step.
