Funny smell from air conditioner

Ok the other day my wife came in from driving the X and said it smelled like trout. Since I am not a fisherman wasnt sure where the smell would be coming from. Then I went out and turned the A/C on and the smell coming from the vents did indeed smell like fish. I keep my garaged all the time and do not have signs of rodants or anything so I tried to eliminate anything that might have crawled up in there and died. I dont know. Has anyone had a funny smell come from the air blowing out the vents and have had any luck getting the smell removed? I will tried some kind of air freshener but wondered if something more efficient would do other than hanging a freshener from the mirror. Maybe there is something I can put down in the fan housing or something. Any thoughts would be greatly appreciated.

Re: Funny smell from air conditioner

The A/C in the Ex. seems to get musty pretty easily. My Expedition did some, but not this early and not as bad. The more it runs the more is clears out but I don't like getting that nasty smell blown in my face.

I try to run the fan without the comp. on before shutting down which works in most cars, but not this one.

Ford supposedly has a really good freshener that kills all the stinky crap in the vents. I'm sure others may have other suggestions.

Re: Funny smell from air conditioner

I read in my 04 Excursion manuel to leave the vents open, that is turn off the A/C and just go to outside air (ie heater). This will help with the odor. On mine, I have tried it and yes it does help. My X sits for days/weeks at a time in the driveway....which reminds me, I need to go change it from A/C to just vents...been sitting now for about a week.

Re: Funny smell from air conditioner

remove the fan under the hood and spray simple green on the condensor...let sit a few and then rinse with water hose..(yes it will drain out the bottom)'ll smell good and will blow stronger and colder afterwards..

Re: Funny smell from air conditioner

Not likely the case...but once I had a male cat "spray" in the engine compartment in my car (many years ago). The smell came through the vents so that I couldn't use the AC or heater (oh man, the heater was MUCH worse). I have to say, it was a HORRIBLE smell and quite revolting.

If you were parked somewhere where there was a just never know. I hope that this isn't the case for you though, as it took MONTHS for that smell to go away!
