I think I may have this issue on my 2003 Protege5. I am struggling to remove this trim to get access to the drain. I loosened the screw, it is very loose on the left side but seems stuck in the top right corner. Any idea why?
you could clean and disinfect your evaporator and the smell will go away for some time.
A proper ac spray would help and can be sprayed through the blower motor below the ac cabin filter.
Its highly unlikely your drain pipes are clogged so early.
first off you guys are awesome!
My 2019 (54k miles) started doing this the last week or two and this video greatly helped.
I did notice the hose is slightly different on the 2018 as it didn't have that retaining clip on the top part of the drain hose.
I was able to get the kool-it line all the way into this hose and emptied the can into the line.
had some discolored fluid leak out of it into a container while I let it sit for 15 minutes so you could tell it was definitley cleaning it out.
After starting the car up it appears the smell is greatly reduced / gone but I'll keep an eye on it the next few drive cycles.
one interesting things is I drove the car around for about 10 minutes after cleaning (with that kick panel removed) and I did see a bit of water on my floor mats. Not much but dripping from somewhere.
The drain line doesn't appear to be clogged as it was dripping into a tupperware container earlier so maybe it's just some extra condensation / fluid that I missed earlier. Something to keep an eye on the next few days.
