Yes the dealer has a special machine that sanitizes the AC system and kills the mold that causes the smell, the chemical they use is not approved for sale to the public so they must do the job.

2003 aztek water on floorboards, not solvent

theres a box under the dash with a filter and drain tube they are what's probably clogged. your best bet is to get a Hanes book or chilton from your parts store to walk you through it if your set on doing it your self but I will warn you it's a job and it's aggravating.

How do I change the cabin/aircondition filter

the 95-99 honda odysseys supposedly do not have a cabin air filter. I discovered this when I tried to get a shop to replace mine. However there is a chemical spray that can be sprayed into your dash to kill of any molds or gunk in your vents if you are getting odd smells.

Hello there,when i starts z car in z morning,blue smoke comes out.Is that normal please.And z car miss fires if i accelerate suddenly.I have changed z distributor,spark plugs n wires.Z car is of carburator...

The blue smoke is OIL, coming from bad seals in the valves. It drains into the cylinders overnight and when you start the car it burns the oil off. This is probably fouling your plugs and if backfiring will fould the carburator. The miss firing is due to the age and most likely the timing of your engine, along with fouled plugs and carb.

Foul smell with air on circulation

You either have a heater core issue or what is real common an all cars is you may have a mold issue on the AC evaporator that is burried in the dash ductwork. If this is the case all manufactures have a cleaning process that requires partial disassembly to allow a spray wond to spray a mold killer into the problem area.

Usualy this problem happens because you keep your AC on automatic mode or you always run you AC and never give you vents time to dry out.

If the smell can be desribed as say a locker room type smell then this will be your problem. If it is a mold issue it can cause health issues if your suseptable,

If the smell is sweet and your loosing coolant then it will be a heater core issue

09 sonata with 1000mils on it with a/c off foul smell comes from ventilation system with fan on. no problem when a/c is on

Does it smell like a dead animal? or just moldy mildew smell? If dead animal, get it out. If mold/mildew smell, treat it with an AC ventilation dodorizer.

YOu either have something dead in your heater box, or your A/C evaporator core is molded up, and will need to be replaced.

Air conditioning bad smell

Richard you have to check if your car uses to filter the air-conditioning closed the lid of the engine and where the breeze is a clean-clean grill before you turn off your air off the compressor and that was only working to remove the blower evaporator at all moisture-check that you have good drainage evaporator vote you all that water. Thanks and good luck
