There is a sickly sweet smell coming from the heater vents. How do I fix that?
Model: E 350
hi, i'll be happy to help you in anyway i can.
sorry to hear of your misfortune :(
you have mildew in your heater box.
there are some aftermarket products that work reasonably well for eliminating it.
in rare instances it requires major disassembly and cleaning.
i would start by having you mechanic remove your cabin filter and treat the heater box with mildew elimnator and change the cabin filter.
good luck, gary
p.s. avoid using the recirculation button, it contributes to the problem.
