Just curious if anyone has ever attempted cleaning the evaporator through the blower resistor. There is a TSB for this, but it applies to older toyotas, just wondering 1) can this be done on the 9th gen corollas, and if so, where is the location of the blower resistor? TIA

I did some digging around the blower motor, and I found something similar to the resistor in the second link I posted, however it is not located directly in the evap housing like it is in the celica. I was looking for a way to clean it, I guess I will try cleaning it through the center vents to get rid of the gym bag odor I have when I turn on my AC.

I'm guessing you've already checked that the evaporator drain isn't clogged. When I go through the annual cabin air filter changes, I vacuum the system through the filter opening before I install the new filter. I have had good luck with a product called "Frigi-Fresh" http://www.bgprod.com/products/climatecontrol.html for killing evaporator mold odor, and I spray that into the evaporator when I change the cabin filter.

I was looking at using Frigi-Clean, but I think I will go with klima cleaner. How do you apply Frigi-Fresh to the evaporator? In the vent intake? I checked the drain tube and it was fine.

I just spray it into the evaporator through the opening in the side of the HVAC with the cabin filter out and with the fan turned on.
