Okay, I found a TSB for fixing the odor from the A/C vents. This procedure also tells how to access the evaporator. I think I'm going to do it, just so I can see if mine is dirty. Below are parts of the instuctions that would pertain to accessing it to clean it:

1. Open the hood.
2. Disconnect and isolate the negative battery cable.
3. Remove the silencer pad from under the instrument panel on the right side to gain access to the blower motor.
4. Disconnect the blower motor wire harness connector and remove the blower motor.
5. Inspect and remove any leaves and debris.
6. If necessary, use a shop vacuum to clean the cooling coil.

To remove blower motor:
There are three screws holding it in all located on the front (if you were looking at it from the inside of the car). Tighten the screws to 2 N.m (17 in.lbs.) .
