With the engine running and your HVAC fan running at MAX speed open your hood and spray Lysol spray (blue can prefered) into the air intake below the wiper blade on the passenger side (Called the Cowl). You will see the Lysol being sucked into the A/C Vent system. Do this on and off for several minutes. The Lysol should clean out any nasties growing in your vent system. You may need to repeat every day for a week or two if nasties are severe enough.
Vinegar smell coming from AC Vents
Hi All,
I have a KIA Sorento 2.4L Petrol 2014 FWD model (I purchased it in 2015 and its in Kuwait) .
The car has done 98000 KM and I changed the AC (Compressor and Evaporator both under warranty) at around 85000KM . Now when I switch on the blower a smell like vinegar is coming on and when the AC is turned on, the smell goes off. When I switch off the AC and if the blower is running the smell is back.
I took it to the service center and the cant find it out. Can anyone show some light into this issue? Is this a bacterial issue or something with the blower? Am sure that nothing has spilt on the dash from my side. No idea whether anything happened while the guys changed the AC.
Kind Regards

Yea, if held on constant spray. What you want to do is pulse the spray, on for a few seconds then off. Use some common sense and don't drown the air intake system. You can also do this in your homes HVAC system. It helps keep the duct work free of mold and mildew....Don't do with the furnace running!Wouldn't that wet the cabin air filter and choke it while its wet?
Yes, you could do this, but most folks won't because getting the cabin filter out requires some effort and auto knowledge. Getting Lysol on the filter won't hurt it a bit.Wouldn’t it be better to just take the filter out while you do this. Seems like your mostly just spraying Lysol on the filter.

Switch over to flow thru vent. Follow my Lysol procedure as described above and repeat weekly for one month. Report back to us in 4 weeks letting us know what occurred.
Thanks!
Yes, I do it my home system at least once a month during cold and flu season.Actually I was thinking of your suggestion to do it in your home system.

But, I live in the South, where the cold air returns are only on a main floor in a wall. Much different than up North where cold air returns were in every bedroom and room and the furnace filter was in the basement right next to the furnace itself. I just drop the access door against my leg, drop the filter against the access door and with the furnace fan running spray 5 second bursts into the cold air return for about 30 seconds. It kills mould, mildew, and any virus / bacteria lurking there.
