It is possible that the hot water coil is leaking, and the cold air running mixing with hot damp air will cause the humid smell issue.
This normally indicates a refrigerant leak. STOP USING YOUR AC IMMEDIATELY AFTER THE ACKNOWLEDGEMENT OF THIS SMELL!! The fumes from the fluid in your AC system are highly toxic. The leak needs to be sorted out before the AC can be used again.
The musty smell in your car's AC is often caused by mold or mildew growth in the system. This can happen when moisture gets trapped in the system, creating a damp environment where mold can thrive. Regularly changing the cabin air filter and running the AC on high heat can help prevent this issue.
If your ac is working well and is on in humid weather it will dehumidify the air and can drain quite a bit of water which you can see especially well when stopping the car it will drain underneath the car usually near the firewall in the desert when dry it might not drain at all but the more humid the more water, it can seem to just be pouring out!
Several thing scan cause a burning smell from a car A/C. One cause can be that the compressor is burning up. Another possibility is a wiring shortage.
Sounds like your compressor is locking up.
The smell of mildew in your car's AC system is usually caused by moisture buildup in the system, which creates a breeding ground for mold and mildew. This can happen if the system is not used frequently or if there is a clog in the drainage system. Regularly running the AC and cleaning or replacing the cabin air filter can help prevent this issue.
Any smell from the car vents is unrelated to the AC system unless it is an antiseptic smell. Generally, the smells are environmental from your engine compartment, where the fresh air is taken from. If you smell something burning from the vents, then something is heating up to much under your hood. Check your compressor for a worn clutch, or oil leaking onto the exhaust manifold.
this kind of thing happens in my durango when i have the ac on and its humid inside the car.
My car had fish oil poured down it I used a product called What Odor? it completely eliminated the odor i recommend trying What Odor?
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.
There is a fuel leak in the engine compartment. Have a mechanic look at the engine.
ya it probably smells like feet right? the problem is you probably left the car out in bad weather for too long, park your car where its safe then turn it on with A/C on and leave it for about 20-30 minutes.
