Yesterday I was picking up my daughter from school and this pungent smell filled my cab. Thought it was outside but then realized it was coming through the vents. Back on the road it dissipated.

What can this be?

Thanks.

 

Ive heard of a moldy smell, but never dead... Wonder if something died, but then again if it quit going down the road who knows... Doesit do the same on Recirc and Outside air???

 

Depends on how much you run recirc, and what part of the country you're in. Around here it is so humid that condesation builds all the time, and on a really hot and humid day it builds alot of moisture on the evaporator. Where there's moisture theres mold. Nothing toxic normally but certainly nasty smelling. Since all fresh air comes through the evap you will smell it mostly at start up before you are de-sensitized and it seems to go away. There are numerous products to clean this but the easiest is by BG and called frigi-fresh. You can find it at most new car dealers in the southeast. Chrysler had a similar product and process but many $$$. The frigi-fresh works just as good.

Naw, it was pungent... like something nasty burning. Think hair.

I live in non-humid mostly sunny northern cal.

I was just curious if this was a sign of something going south in the system.

 

sounds like you were smelling something dead coming thru the ac and when you left that location it went away?? Not sure, but I doubt its something caused by your ac going bad!

 

I had the dealer treat my vents and plenum yesterday when I had the truck in for an oil change. Here in the Mojave you have to run recirc all the time to get the cab to cool down on 115 degree days. They treated it free of charge and now no more stink.

 

Have you checked to make sure something didn't crawl up in the engine and die? If you get more air moving through the engine compartment maybe the air isn't going into the vents then. Just a thought.

 

Hmmm... you may be on to something there. I didn't drive it for 4 or 5 days... lemme have a looksie.

I could tell you about the time I was working on an old Mazda pickup... my father's old ranch truck and contorted deep underneath and wrenching there for awhile I looked up and within a foot from my face stood the well preserved skeleton of a big-a$$ RAT staring straight at me. I'll bet that smelled real purdy at one time...

 

There is a TSB for stinky A/C's. Hope this helps!!!

 

I had a field mouse crawl into my ac ducts somehow. It started with a trip to work, when the ac fan just started making a horrible noise, like a bearing out or fan out of balance. After a day of it closed up in a hot parking lot, there was no question about what it was. He was all hacked up and well puffed.

 

Serious? Where can I take a look at the TSB's to find that? I think there's an online source, eh?

 

Sorry don't know how to do links. Work better with tools not keyboards. The TSB is HERE

P.S. I just figured it out!!!!! the link thing.

 

Mine had kind of a funky smell to it for a bit, but has since gone away
