Could be oil burning, rubber burning on the exhaust from a plastic bag, could be a fried blower motor. There are many possibilities here and only a hands-on inspection can determine the cause. Use this link to find a good shop near you. https://repairpal.com/repair-shops Alex

raise the hood and look it over under there,see if you see anything that don't look right,may be a pulley seized, or like Alex stated,could be one of several things.
