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?

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.

Hope this helps.
