Blower Motor on 2004 Pontiac Grand Am

When turning on the heat in my car, it smells like something is burning. I have been told it could be my blower motor. Is this a corrrect assumption?

Does it smell like "electrical burning" or "a sweet smell" when the heater/heater blower is turned on? Several things could be happening. The blower motor could be failing, a mouse or rodent could have bee nesting and deposited debris in the heating ducts, leaves and debris could be ingested into the ventilation system and are decaying or caught up in the heating system. If you have mysterious coolant loss, or the the windscreen fogs up or you smell a slightly sweet smell in the car when the heater is operated the heater core/heater radiator may be failing or sprung a leak.
It is not a sweet smell at all. It does smell electrical.
