Baby Sick Smell!

[PW39]

How can I get rid of this awful baby sick, sour milk smell coming out of the air vents of my ’99 Avensis.

It’s there with the air condition on or off.

At the last resort I took out the pollen filter, posted about in another topic.

I thought that had done the trick and was on the way to addressing the root of the problem but the smell returned with a vengeance.

I have used four of those aerosol things you set off behind the front passenger seat but the smell is still there.

Any ideas please.

Check where the air enters the ventilation system in front of the windscreen? Maybe theres somthing causing it there. If not You may have to start stripping down the air pipes in the dash to find the the problem.
