Have this Musty smell from the Defrost/ AC Vents as I'm sure everyone has heard...suspect mold in the Evap/Condensate chamber... Tried the MOPAR spray and hit all the vents and Defrost Vent... It masked it for a bit then returned. Finally I purchased the foaming Evaporator Cleaner. Instructions say to spray it into the Condensate Drain Tube... However I'm having trouble finding it. Anyone have any ideas? I've looked all over from underneath and can't seem to find it off the firewall. Maybe I'm missing something.


If it works out I will be more than happy to post the product and result findings. Thanks!
