Hyundai Repair: smell from conditioner, hyundai electra, ac coil

Question

I bough Hyundai Electra 2005 on November 2004.
I have noticed bad smell in my car on past year  summer. It happened sometime but not very often, so I almost did not pay attention on this. But this year, when I start using conditioner,   I feel smell inside of car  more and more often .  I thought I can not turn on conditioner correctly. But I did not figure out what is correct way to turn on conditioner, because   there in no connection between how I turn out or turn on conditioner.  Sometime I feel smell, sometime not. But, as I said above, now it bothers me more, because it happens almost all time.
Please, advise what I should do.  

Answer
You have to get an ac coil cleaner kit an clean the coil in the car its moldy thats your smeel an after driving with ac on let the car run for about 2 min with ac off an let it drain down after you clean it every time you use it this will help the ac problem
