Fishy Smell While with A/C?!?!?!

Just moments ago, I cranked my WK and as soon as it turned over, I heard a noise that sounded like water coming from the A/C vents. The A/C was on when the WK was cranked.

It sounded like water hitting a fan. A/C still blows cold but immediately after the noise came a wry bad fishy smell that sticks in your nose.

What's going on?

Thanks in advance.

Re: Fishy Smell While with A/C?!?!?!

Not sure. Could be a bunch of different things that could be causing that. I had a car with a design flaw that would let water enter the fresh air intake grille - causing water to get into the blower motor.

Perhaps have dealer check into that for you. Wouldn't want anything like that to be an issue for too long. As you know, damp places are the perfect breeding grounds for certain things.

Smell could be coming from the cabin filter that could be dirty/wet?

Thank you for your reply.

It most certainly sounded like something busted when I cranked the WK. Is there anything I can look for to trouble shoot?

I'm looking up "fishy smell ac vents" on Google and I'm seeing a lot of things about the heater core.

Re: Fishy Smell While with A/C?!?!?!

I would check the air inlet and check if there are no leaves or other dirt blocking the area or blocking the water drain holes. An other item would be checking the HVAC housing drain, which ends in the engine bay.

Ok. I have no idea where to check for all of this stuff though. I honestly don't see how this would be the cause of pouring water sound and fishy/chemical smell coming from the vents.

I will also add that I was idling for a while with A/C on before turning the WK off. Then all of this started after cranked it about 2 hours later.

I do sit I'm my Jeep with A/C while idle every once in a while.

Re: Fishy Smell While with A/C?!?!?!

So now that I'm smelling it more and more, it's smelling like old stale/sitting water. Very very strong.

I just got off early from work and I'm about to go in the garage and look at the intake.

You may also have a badly plugged drain, either in the a/c heater itself or in your hood air intake. I don't recall if your model has a built in drain tube for the a/c plenum or if one has to be installed by a dealer.

A busted heater core should show up as coolant loss, plus unless your coolant is really really old or someone substituted fish sauce, not that likely.

Once you find the culprit, you will probably want to get one of the stronger foam type flushes for the a/c plenum, FrigiFreeze is a bit tame compared to some of the stuff A/C shops and dealers have available.

For the underhood area, try pouring water and see if it comes out at full rate from the drains. If not, it usually works better to declog from underneath so you don't poke anything loose. You can plug the outlet temporarily and pour in a couple bottles of cheap hydrogen peroxide and let it set a while to clean out anything there. Or, you can plug the outlets, cut up some of those denture cleaner tablets and drop them down the drain, then fill with water and let that set overnight.

Cleaning the A/C plenum is to put it mildly, a pita you might want to think about farming out to an A/C shop.

Thank you very much for your response. I have no idea how to do any of what you suggested.

Here is what I did do: I inspected the air inlet thoroughly and found no signs of debri. I didn't find any animals either. I found out that I have no cabin filter while I was in there.

I then pulled the A/C fan and found nothing in it. Just a light trace of dust.

On my 20+ minute ride home from work, realized that the smell has faded a lot but it is still there. After doing all of the above, I went on a 30 minute ride and the smell has not gotten any weaker since the 20 minute ride home work.










I will say that the brown stuff pictured below around around the edge of the fan has that terrible smell. And remember that I said that I heard something moving with the speed of the fan. The sound faded away slowly when I increased the fan speed and I have not heard it since.





How do I check to see if the drain is clogged? Where is this drain? I still see water dripping under the WK but could it still be clogged??

Edit: Watching a YouTube video on the A/C drain now.

Re: Fishy Smell While with A/C?!?!?!

So I watched a couple of videos of clogged WK evaporator drains and these guys had water building up on the carpet and none dripping underneath.

My carpet is dry and I have water steadily dripping underneath.

What next?

I know that. I've checked under there a few times already. There is a little door back in there that opens up. The fan sits right under that door.

Thanks for the help.

Hey bro. I circled where the cabin filter is located. Its under the plastic. This is where the air comes into the ac system from outside.
