That may be an indication that the heater core is leaking.

Are you correctly using the defogger?
Try to use the fresh air instead of the recycled air.
Are you a smoker? Water vapor catches on to smoke particulates
stuck to the inside of your glass thus fogging up quickly.
Also, is your dehumidifier tube plugged? (Does a little water drip
down from under your engine area when A/C on? This is normal!)
If you smell sweet air and foggy, then yup your heater core is leaking.
Or at least a tube to it.
