Bad heater core.
my 2001 mitsubushi montero sport sometimes smell like burning rubber what could it be coming from
Defrost uses the a/c, if it doesn't smell the same with a/c only on. The smell is coming from the blower motor. Bmw's for example have a problem where the blower blade contacts the plastic housing and causes it to rub/melt.
The belt is burning up and wind is pushing the smell through the air conditioning.
Because your burning your clutch.
