See if you have coolant dripping/ present at the A/C condensate drain (where the A/C normally drips from onto the ground). If it is present, your heater core may be leaking.
Sometimes, especially when it is cold weather, you may see steam coming out of the vents.
Everybody's sniffer is different, normally a sweet kind of smell is present.
