How to clean out the car air vents?

I have a bit of a funky smell coming through my car's air vents, regardless of the heat or air conditioning being turned on or off. Is it possible to clean out the vents?



Also, where exactly is the source of air for the vents?



I have an older car, a 91 Cutlass Supreme, so I doubt I have that cabin filter, but are there any other filters that might need to be changed?How to clean out the car air vents?
The 91 Cutlass Supreme did not come equipped with a factory cabin air filter.



The smell coming from the vents is coming from the ac evaporator. The evaporator gets very cold and produces condensation. The majority of the condensation drips out of the drain plug outside on to the floor. However, there is always some moisture that is left behind and it eventually grows mold and causes a funky cheese or foot smell.



There are two ways to deal with this issue:



1. Remove the evaporator and have it cleaned - But this involves many hours of labor and will be costly if you have a mechanic do it.



2. Spray an evaporator treatment foam directly to the evaporator - You will have to remove the blower motor or the resistor to gain access to the evaporator, but it is a lot easier than removing the evaporator.

filter no not that i know of you can blow them out with air hose suck then out with vacuum spray debree or hang a air freshenerHow to clean out the car air vents?
Well it could have a filter - go to one of the websites for your local parts store and see if you can look one up for it. That is usually the cause of a stinky vent. Otherwise I guess you could really have something in there, in which case I don't know of any easy way to find and/or remove it.



You could try some kind of flexible pole with a duster taped to the end of it I guess, a coat hanger comes to mine - the vent grilles should just pop out but if the car is that old, they could be starting to dry out and get brittle so be careful removing them..How to clean out the car air vents?

The air intake is in front of the windshield. The drain is in the two corners next to the fenders. Under the fenders. A black rubber flat tubing. Squeeze it and use something to get what ever might be in there.How to clean out the car air vents?
The smell is from mildew from the sweat of the AC. You can go to any auto part store and get a vent deodorizer. It should come in a spray can.
