gents.
im new to this wonderfull club.
a small issue started when i gave my 2006GS300 to a friend and he was using the AC in Auto mode.
afetr a week i noticed that when i pass by a truck or even a motorcycle, i smell the outside smoke the car even when in the circulating mode.
i changed the filter but no luck. i cleaned the smog sensor and still no luck
can anybody help.

 

Trying using the button with the arrow floating inside the car? correct me if I'm wrong but that's how it was with my other cars because the one with the arrow coming in the car is letting the air from outside coming in no?

 

The third button from the left filters the air. The recirculate button, on the far right, doesn't actually filter the air. It only prevents air from the outside from coming into the cabin.

So ... when you want to avoid an odor before you actually hit it, hit recirculate. If you're already in it, hit the filter button.

 

no. i dont mean the botton that is having the arrow from outside to the inside of the car. and i always have it on the other mode which is the recirculating mode that is not letting air to enter the cabin. which supposingly seal the car cabin but it is not doing so those days.
i think there is a flapper door or something like having seals and the seals are gone or its not closing proberly.
but i dont know where is that thing to go and check it.

 

umm, do you have any warning lights on the dash? have you changed the ac air filter lately?

 

no man, no light...i just changed the filter and i cleaned the smog sensor recently and no luck.

 

when you changed the filter, did you put the system in CIR so the trap door opens?

 

yes. otherwise the door wont open and let u replace the filter.. am i right?
what do you think if the seals or the door is not closing proberly, is it going to cause this issue?

 

ok, so you did it correctly. i am just thinking what happened that can cause that... clueless so far

 

I would say take filter out make sure its in the right position and its not loose.

 

you were able to solved the issue of outside car smoke smell in circultaing mode? having same issue with 2007 GS350.

 

anybody had this issue and the solution for it? smoke and outside odors with air in recirculating mode max cool.

 

I like to fart first then hit recirculate
