Heater smell

OK, got a new problem. I turned the defroster on this a.m., as the windows were frosted up. I came back out to leave, and thought something was on fire; the care was fill filled with the smell of rubber burning. Any ideas?

Wiring to your fan speed control? Perhaps the smell is antifreeze, doesn't smell like rubber to me but you could have a leak. Check to see if your carpet is wet under the dash.

I find that new coolant hoses can somehow give a stinky rubber smell to the vehicle for a while. Not sure if you replaced any, but if you did it'll go away in about 2 weeks.
