Funny thing with my heating system (up here in Pullman WA at WSU, it gets freakin COLD) is that every so often I get this light headed feeling. Whenever someone else rides in it, the tell me they feel sick, "What is that EXHAUST smell?".

I've grown used to it, but usually leave my heat OFF, alternate hands while driving, wipe the windshield with a rag every few seconds... ahh, spring, so far away...

But what really set my nerves was when I saw a thick cloud of exhaust billowing out of the two front vent above the dash!

The heating system is wrapped around the exhaust system in this air cooled engine, no? Maybe a hole somewhere along they way, which is leaking exhaust into the heating tubes?
