welcome
does it smell like burning antifreeze or some thing else? if you live out in the country like I do I have to check from time to time under the hood and under the dash for mice nest but if it smells like antifreeze you could have a small leak some were

Also, is the smell coming mostly from the center vents? I've been researching a little and it may be either the speed control resistor pack or the fan motor going out.

If you have a small oil leak around the exhaust manifold(s) you might smell that through the vents via the plenum.
