Bad Smell

[gx100]

OK, I think I might of picked up cow pie in my vent or something. When the vent is on and out side air comes in there is a distict smell of manure. What can I do??? I tried hosing off the the front and spraying inside of the vents but it still there. It's been over a week.

Check around in the engine compartment for a dead rat. No kidding!

The dead rat, or any animal, issue is possible. I live on a farm and did experience such a thing once. However, decaying flesh doesn't smell like manure.

Have you checked the fresh air/heater/AC filter? It is supposed to be changed every 15K miles. It can get moldy and have a musty odor, especially in humid country.

There are some hints on this site about cheaper ways to get around having to buy an expensive Lexus filter. Some people cut up HVAC filters that are carbon impregnated to reduce odors.

Was your Lexus recently "involved" in a wedding party..??

Or someone POed at you has dumped a "pile" just under the wipers..??

I checked the intake and the filter and both seem clean or at least oder free. The smell is strongest when I use outside air. If i use inside air it isn't as pungent. No dead rat, I washed and scrubed every inch of reachable part. Is there a detergent or spray that I can use in the vent that will kill such a bad smell?

check intake by windshield?

Pull the factory manual and see where the air inlets are.
