sweet smell coming from vents when AC is on for LONG period. can almost be smelled outside of vehicle also.

my coolant levels are fine (filled to the cap of radiator), no signs of it on carpet either... everything is dry (no signs of leak) what else should i be looking for?

freon/refrigerant has no smell right? LoL.

thanks in advance.

 

sweet smell is coolant are you sure ur coolant level is good probably leaking

if in not mistaken there is a drain tood atatched to the heater core to drain any condensasion so thats where the leaking coolent will probably be going

 

Could be heater core or normal... Is your oil-cap, radiator cap and dipstick milky or normal? If so, probably coolant. I don't know but a quick search brought these results/threads
