I have a quick fix for the dust problem in the A/C. It involves flushing out the evaporator with water.
If you get a few seconds of a dust blast or mildew kinda smell when you turn on the A/C, it usually is because the evaporator is dirty. You'll need a phillips screwdriver, a bucket, a flashlight, and a garden hose...(yes I said garden hose)
1. remove the left kick panel. (the plastic panel that would be near your left foot if you were sitting on the front left seat. You'll have to remove a plastic nut on the front of the panel and one screw at the bottom of the door jam (where the scuff plate is) to slide it back. Lift the scuff plate a bit if the kick plate wont slide out)
2. remove the electrical connections to the blower & thermostat under the dash.
3. remove the three screws holding the blower in place. (use both hands, one the hold the blower, and the other to use the screwdriver. The blower should drop straight down when you remove the last screw.
4. remove the thermostat, it has two screws holding it in place and it's a bit to the right of the blower. All the electrical leads are taped together, so you just have to trace the wires to find it.
(all of the above will come out in less than five minutes)
5. at this point you can open and close your external vent a few times to see if anything drops down onto the car mat. Be a little curious and look up inside the vent (use a flashlight,) you'll see that there is no filter and you also see how the air is moved through the system.
6. snake your garden hose in the vent past the point where the thermostat is located. if you put your hand in there you'll feel a foam covered tube. That's one of the A/C gas lines, the evaporator is just behind that. You should be able to hold the hose nozzle easily in there.
7. also put a bucket under the vehicle where the evaporator drain line is, so you can see what's coming out when you run the water.
8. Get someone to assist you in opening & closing the tap while you hold the hose nozzle in the vent. Run the water for a few seconds at a time and try to move the nozzle in a circular motion to cover the evaporator with water.
DO NOT run the water for too long, remember the evaporator drain line is designed to flow water out at a very slow rate, so you don't want it to over fill. and then have water back-up into the interior of the van. Short bursts of water would be okay.
9. Examine the contents of the bucket for debris/dust. If you see stuff empty the bucket and flush again until clear water flows out. (use a white bucket, it would obviously help.) Lock off the water (and hope wasa is not aware of what you did

) and put everything back together in reverse order.
10. Run some water outside at the base of the winscreen to flush out that air intake area. Fire up your A/C and breathe some fresh air.
You can also spray some Lysol or Oust on the external intake at the base of the wipers while the A/C is on (and the external vent left open) to deodorize the system.
The entire process will not take very long, If you're not comfortable with the DIY, just check any A/C technicians in your area. Mind you they might want to tear down your entire dash and charge you up to $500 dollars to do it.
