ac odor

I have a 2000 grand marquis which has had an odor whenever the ac is first turned on,the dealer since the car was new has not been able to correct it,including two deodorizings and the installation of an fan afterun which senses moisture in the system after the car is turned off and runs the blower untill there is no longer moisture but still has it.Has anyone found a perminent fix?

i have a 92 grand marquis and all i did was spray a can of lysol in the intake for the sir sytem with the system on vent and it hasnt stunk scence

hey did spraying the lysol work cuz id like to no thanx

I haven't had the chance but will let you know as soon as I do,thanks for the feed back.
