I just started noticing the other day that if I turn the defrost on and I am at idle I can smell exhaust fumes in the car pretty bad. Not sure what could cause this or why it's happening.... Anyone have any ideas on how to troubleshoot it?

I had a leak in the emissions equipment, same thing happened to me.

Whatever that little box is on the front of the engine, silver looking thingy that has a pipe going to the exhaust manifold. It was bypassed when I bought the car, the ghetto bypass came out, which spewed exhaust into the engine compartment. Hooked it back up, works fine now.

Check all your emissions stuff, lines, etc.
