strange air con smell


Recommended Posts

Over the last few days when i have turned the air con on, it has a weird smell to it. Wouldn't say its a musty smell, Cant really describe it. how would i go about checking what the smell is? Could it be the cabin air filter in the glove box perhaps?

Exactly what I was thinking. It will do no harm to check and clean the air filter. Maybe even give it a spray with GLEN 20 or similar.

Yep.  At a guess it’s been quite hot and humid weather as well?

Pop out the cabin filter,  turn on the A/C and run the FAN at full speed, and also put the heater on maximum.

Then spray a can of Glen20 into the slot the cabin filter would be in.

What this does is distribute the Glen20 through the vent system, in particular on the heater and AC coils which is where the majority dank was comes from.

Glad it seems to have been sorted Steve, the cabin filter is basically first line of defence with incoming air to the cabin so for the price of the filter it is always worth checking and changing regularly.

Hope it has that smell sorted now mate

The smell has returned 🙄 smells like vinegar.

Hey Steve!

Few question to try out or check first.
 

Assuming your car hasn't got any leaks inside (and the problem is from the aircon circulation itself) and you've bought a new cabin filter and put it in,

Your profile says you live in QLD, something that can help any mold buildup in the ducting, is to park the car in direct sunlight (easy now it's summer) and have the windows down, doors open and leave it like that for a few hours. Every now and then, start the car and turn the interior fan on for about 15 minutes, then turn it off and let it sit again. Keep this going for about 5 hours. (annoying I know) This can cause the hot air to circulate through the ducting and kill the mold buildup. I had to do this when I first bought my Aurion in 2019. The smell of the melted dashboard and a moldy smell from the aircon...it was gross to drive. QLD-dry out and a dashmat fixed it for me though. Haha

Lastly an idea would be to just bomb the car with 4 air fresheners overnight (with something neutral like 'new car scent'). Not to clear the smell for the morning, but to stain the smell in the car so when the aircon circulates (if you use recirculate) it's getting a scented smell.

Another note: do you notice the smell at a certain time while driving? When merging onto a HWY or taking off with pace? If so, chances are it's not the air con at all. It's probably just the sulfur smell from the cats that we all get. 😁

I get this smell when I accelerate hard (or sometimes when towing) even when the system is set to recirculate. It's rather annoying.
