AC Smell

[ry0de]

I was wondering where the A/C drain is located. I have a moldy/mildew smell that happens when the A/C is turned on. I tried using the deodorizers that you leave in the car, but that only works momentarily. I also replaced my cabin air filter and that didn't do anything. I plan to replace the air filter again, but I also want to clean the A/C drain to get rid of the smell. Is that what I should do?

The evaporator is what you would want to clean, not so much the drain hoses. They sell a can of evaporator cleaning foam that you shoot into the HVAC housing from the filter's air channel.

Change the cabin filter.

Whoops, didn't realize he changed the cabin filter.

Buy a can of AC cleaner and spray it in the hole of the temp sensor on the evap core. Additionally you can spray it in the vents to reach as much as possible.
Let it sit for like 5-15min depending on what you are using, then turn on the heat and fan on max and let it run for 15min to dry. I used the AC cleaner from Liqui Moly.
This solved my issues in my BMW F series I had. Supra will be similar.

Have you tried an air freshener?

Just looking for an update from the original post? Did this get resolved, if so, how?
