Hi,
I think My Lexus 2007 IS250 doesn't circulate the inside air because:

• when I push the button to change the circulation mode it doesn't make any sound. (The mechanical sound - Like other cars)
• when I drive the car and the AC is OFF, I feel the air is coming from outside (even it has been set to circulate the inside air last time and AC is OFF).
• Sometimes I feel a bad smelling inside the car when I push the gas pedal hard (something like smoke)
• I feel outside's smell (even when I set the AC to circulates the inside air)

I changed my air filter recently. anyone has any idea what is the problem.

Did you change the setting to recirculate when you changed the in-cabin air filter? If not, you probably broke something that is not letting the car change between outside and inside air.

The cats over time won't work as effectively as when new. The rotten egg smell is the cause of a reaction from the primary and secondary cats when at WOT.

sound like changing air filter without putting the car in recirculate mode

I agree, sounds like the poster needs this thread: https://www.clublexus.com/forums/is-...g-to-circ.html

Thanks, guys, does anyone know if there is a way to find out that part has been broken without opening the passenger dash.

Open the glove box and remove the cover like you are going to remove the air filter. Just remove the cover, not the air filter. Turn the ignition on and press the buttons for recirculate on and off. When you press recirculate off, you will see a plastic panel come down and block your view of the air filter. Press recirculate on and the plastic panel will move out of the way.

^ great post. Did not know that.

I gave my Toyota service dept. a printout of the page saying to close the recirculate when changing the filter and they still broke it. They made it right though.

I'm having the same exact problem, also note that I didn't touch the air filter and I the mechanical sound when I press the circulation button.

Where to find the settings that you referring to, I guess I didn't change any settings.

aisalit

I didn't change the filter, and I will ensure to do what you said.

Thanks for sharing this

aisalit

you'll hear a voice in glove box when you press the circulation button On and Off again.

Exactly, this is the perfect way for that.
