there as been a sour smell in my car for a while,seems to be coming from heater. some times its ok but if i drive hard it gets worst, it dosent smell like anti freese when im driving but it does when i first get in. i brought the car to a honda certified company, they checked it out but cant find any problems. :says they think it could be hot exhaust. i do have a dc sports full exhaust system on it, does any one have any ideas on this..

 

Is the exhaust system new?

I had a bad smell from my exhaust system for about 3 days after I had it installed. My mechanic warned me that it would smell for a while, until all the fabrication chemicals burned off.

 

Perhaps it is ze' smell uv ze' poopie coming frum de' ventz.

Auf Wiedersehen

Seriously though, I would've said anti-freeze, but you said it doesn't smell that way.

 

I seem to get some of that when the heat is on.

 

I have an LX,when i first got it no smell; BUT now when i either turn on the a/c or the heater i get a weird funky smell too. Not sure what it is though next time i take it to the dealer i will ask them to service it or something.

 

It's the smell from the moisture that condenses there when you last turned it on. Try leaving it on for a while next time with just plain air blowing to clear out the moisture so next time you turn it on you won't smell anything.

 

yeah happends to me aswell only when i dont use the air for about a couple of weeks. Just let it on for a couple of minutes and it should go away.

 

It could be mold growing in your vent ducts, if it smells nasty but more biological(ish) then I'd try sparying disinfectant into where your cabin filter sits while the fans are on.

 

you could also try changing the filter behind the glovebox for the air ducts

 

i know for sure its the air filter happen in my rx330 before too same situation.

 

When was the last time you showered? jk

 

My wife's CRV did this. Smell was not the anti-freeze. I changed the cabin air filter and it stopped the smell.

 

It's probably that dead mouse sitting on top of the cabin filter....

My 2005 Honda LX was BAD BAD BAD about this. Stank horribly after using the AC system. It's the moisture that condenses within the ducting. I was told that the easiest way to get rid of it is to spray Lysol into the intake duct while you have the fan on high (make sure that you aren't set to recycled air ). I personally haven't tried it, but I do think that it would work.

 

sorry about post resurrection but i was wondering where the cooling system intake duct is so ican try some cleaner into the vent?

 

glad u brought this back!
Just a few days ago i redlined my car and there was this weird sorta plastic-burnt smell but idk where it comes from?
Maybe a plastic bag got stuck underneath and the exhaust burnt it but still...i found nothing
this is making me nuts when i drive bc even at 3K RPMS i can smell it and its getting worst and worst!

 

The smell comes only when you follow too close to a Toyota

Could be a burning clutch. That's an awful smell

i know it's WEIRD!
but what do i do now? :S i can't take it to the stealership just yet i got classes in themorning and afternoon with long breaks then work at night...agh

 

I would take it as soon as possible, otherwise you're looking at replacing a clutch AND the flywheel possibly!

 

I get all kinda odd smells from my heater... anywhere from the range of burning oil to rotten fruit... makes no sense to me at all.

same smell is coming out from the exhaust...
and it clearly smells like burnt plastic...
don't wanna take the bus to school that's lame and freezing besides i haven't used my warranty yet

 

could be if you didn't break in your car...

anyway, so anyone on the air intake inlet for the cooling system so i can spray some of that lysol in there?

 

i found it...a plastic bag was INSIDE the exhaust lol

 

nobody to answer my question?
