Cold air blowing and overheating



Re: cold air

there are 2 hoses that come from behind your alternator and lead to the fire wall, warm up the car and see if these 2 hoses get hot. if not you may have air in your system or a clogged heater core, air is more likely. or your actuators took a dump on ya and are not turning the blend door.
