The AC can smell bad due to mold or bacteria growth in the system, dirty air filters, or a clogged condensate drain. Regular maintenance and cleaning can help prevent these issues.
Perhaps a dead mouse.
you have a bad heater core in your vehicle
Your AC may smell bad due to mold or bacteria growth in the system. To fix it, you can try changing the air filter, cleaning the evaporator coil, and using a disinfectant spray designed for AC systems. If the issue persists, it's best to contact a professional HVAC technician for further inspection and cleaning.
Yes. get is serviced. The water under your car is nothing to worry about this is humidity extracted from the cars interior when the AC is running. The smell - no idea what this is if it comes from the AC itself then there must be some mold formed in the AC pipes etc.
I cured my bad smell in my 2007 Sienna with a $10 can of "friggie Fresh"(sp?) from Auto Zone. There are many brands, The stuff kills bacteria in the AC. With car running and AC on, spray in the vent opening behind the glove box. First, take out the AC cabin filter that is behind the the glove box, then spray into the opening to run it through the system. Maybe replace the cabin air filter at the same time, about $15-$20. If you have rear AC, spray it in the intake(return air) vent that is on the right side when you open the rear door.
Could be a bad compressor.
if you have the ac on to long it starts to stink cause the filter picks up the smell and the smell spreads i suggest you get it cleaned
Change the filter and clean the coil. If it smells like a dead animal clean your duct work.
take the dead mouse out of the vent.
Most likely the water drain line from the AC evaporator is plugged and the condensate water and dust inside has fermented. When you park at idle with the AC on there will soon be a pool of water on the ground in he area behind the right front tire. If you don't have any then find the drain line and clean it. A leaking heater core can put antifreeze in that box also and it is not a pleasant smell.
turn on the ac and open the door or window
