Every time the heat is turned on the engine fails. There is a burning rubber smell and rubbing/dull squeaking noise coming from the engine.
Do you
have the same problem?

Absolutely sure that the alternator is not the problem. Charge on the battery is fine. Only have problems when turning on the heat/defrost etc.
