I have a 2004 Lexus es330 with 167,000 miles on it. It is a nice (secondary) car but it has an AC issue. Wondering if anyone in the group can help me diagnose what is going on?
the car has a musty smell even after deep cleaning and running the ozone machine
I have noticed damp carpets mainly on the drivers side. The insulation mats under the carpet were also very wet.
The AC drain plug is dry with no water under the car. No water came out when I ran weed eater string into it to remove debris.
I did a dye test and recharge. The refrigerant gauge was actually in the green and I charged a little more (but didn't over charge.)
unfortunately, during the recharge the clip from the low pressure line to the cabin (see photo with red circle) fell off. I think it was half off anyway.
Below are photos from the dye test, but I'm not sure how to interpret it. I noticed that anything silver seemed to glow under the black light.
I don't see any indication of a refrigerant leak. Wet carpet mostly likely means clogged sunroof drains especially since there is water on the drivers side the A/C system won't do that.

Thank you very much. I did pour water down the sunroof drains and run weed eater string through them. I did not find any indication of a clog there.
