Anyone change this themselves? how do you do it?

 

It is behind the glove box, the filter just slides right out. I believe the instructions are in the owner's manual.

 

thank you!!! I got that horrible smell when I turn the air and heat on...figure its that time to change it.

 

I've found that the mildew smell from the A/C is noticably bad when I've parked the GX overnight with the air recirculation switched on. If I switch it to "fresh" before shutting off ignition (give it a couple of seconds to switch over), then shut down, the smell is pretty much non-existant when restarting later.

My theory is that when switched to "fresh" moisture on the evaporator dries off better since there is a pathway to outside air. If the moisture sits on the evaporator, that's when stuff starts to grow on it and cause smells. Perhaps a dirty filter will also restrict airflow even when parked in "fresh" mode, so a new filter may help as well.

Chek the Denso part number on the filter and see if you can get the filter at Toyota rather than Lexus.
