Could be many things. Can't say exactly what. But, here are a few things I would check. Do you have trees in the area you park your car? If so, you could have leaves pine needle or other dibree in you heater vent that could have caught fire from your heater motor. I actually had this happen once, it filled my pickup cab with wood smoke. It smelled like that every time I used the heater until I sold the truck. You heater core could have a leak and the antifreeze smell could be coming through your vents. Or your heater motor itself could be going bad and melting the winding on the motor armiture. I'm sure there could be other things like electrical shorts, lost cigar behind the ashtray. Hope that gives some help.

Why does a smell like something is burning come through the vents for only a couple of minutes when the car is started in the morning?

The possible explanation for the smell may be that the heater core in the vehicle has a slight leak, therefore the smell of evaporating antifreeze will come through the vents until it is all dried up. Solution is to take the car to a garage and get the heater core replaced.
