Bad Smell. Like Vomit

Well I'd thought I'd ask this question here. My friends' 96 Neon 2dr has this horrific stench inside. Smells like puke. I've cleaned off the floor and checked under the seats and theres nothing that could be causing the smell on the floor. I think something might have crawled into the dash area and is decaying. I've already sprayed some Windex into the Fresh air inlet in case it was there but it still doesn't smell too good. Any insight/solutions will be wonderful.
Thanks.

The only suggestion is to POUR a whole bottle of febreeze into the fresh air vents and to check the accuracy of your sig because I'm not using firefox, but I am using windows XP!!!!

LoL. A whole bottle? I heard Windex was better cause the ammonia kills the molecules causeing the bad smell.

HEY what happened to the sig thing? Oh and I don't know about the windex thing but I do know that the whole bottle of febreexe thing works because I've had to do it on my dads S15, it smelled like catpiss on the inside and well the febreeze helped a little when I sprayed it on the inside and then I sprayed some into the vents, and it helped a little more, so I just got frustrated and POURED the rest of the bottle into the vents with the vent on hi and haven't had a bad smell since.

Maybe some water is getting into the car and soaking into the carpet and pad and causing the nasty stench.

wow u must be one really good friend.. i kno i would never clean the whole interior of one of my friends cars.. especially if it smelled bad
only if i raced and lost and that was the bet or somethin lol

theres a tool called a smell-o-meter where u can hold it and it will point u in the right direction of the bad smell.... i bought one off ebay

<insert funny smiley here but i dont know how>

lol by the way dont do what drunk-pimp did and pour a full bottle of fabreeze in the vent... he probaly did that and then turned it the vents on and inhaled a ton so he could get high....


lol im just kidding by the way

Meguiar's has an odor eliminator product, maybe it would work better than Febreeze ?!
Also, it might be mold in the A/C, there are products (Kleen something at least for Mopar) that disinfect and remove the mold.

Try steam cleaning the carpet, floor mats, and upholstery. You can rent a team cleaner from any grocery store. I steam clean my car twice a year and it keeps the interior looking (and smelling) like new.

try the frebreeze auto care that stuff works good
