Hello,
I figured out where that mildew smell was coming from, its inside the doors! I've used a long plastic ty-wrap (wire-ty) to push up into the four drain slots under each door. It is completely free on both, no clogs or water draining. If the windows are 'up', no smell. If the windows are 'down', the smell is there. Could there be something else blocking or harboring water to create this bad smell? The AC drain is not the culprit. If you smell inside the two rubber window seals at the top of each door with the window down, phew! Please help.
Best regards,
RG
