Terrible musty odor coming from the Defrost vents. Thought it was wet blanket in the back from the beach, or floor mats. Cleaned and shampood them, no change. When I turn the air on it blasts the smell in your face. Where do I get the cleaner/disinfectant, and where do I spray it to get it into the system.
Musty odor inside vehicle
We've got a musty/mildewy smell when the air con is on. Was going to replace the cabin filter but wasn't sure if that would fix it or not.
Musty Odor in AC System
A weird smell every time I turn on the vents
Bad oder coming from hvac system.
Musty smell coming from ac unit
No smell in recirculate mode. Smell is more of a dried leaf and dirt smell, believe only way to get rid of it is to physically clean evaporator/heater core compartment.
When starting car a horrible smell comes from the vents. It doesn't go away but it's less intense after a few minutes.
Smell coming from the air vents when just "vent" is turned on.
Bad smell from ac upon start up
Crank up car, turn on AC, blowers start blowing, yucky smell start coming out of the AC vents...
a musty odor coming from the HVAC system,
Moldy/Mildew smell coming from HVAC system immediately upon start-up. Seems to happen in warmer temps (A/C?) although it has happened at times in the winter. Doesn't seem to smell in very frigid temps. Dealer can't "replicate" the problem so I'm going back and forth with them to do something without me having to take it in again when the problem is detected.
Order coming from vents whenever we turn on the defrost/air. Just stinks!
Nasty AC smell. Shop used the evaporator coating and it worked for awhile, but the smell returned.
Horrible odor in vents actually makes me sick to my stomach. You buy a new car only to have to deal with issues after issues unreal. NEVER buy a dodge. Worst mistake i ever made. Hate it!!!!!
Same problem when I turn blower on hot or cold
