i have a corolla and a buick regal with the same problem for the regal it had stop leak in it before i bought the car resulting in a partial clog in the heater core (very easy to clear out either with a hose or with an air compresser or I've "heard" that switching the input and output hoses can do push the clog out (you can reuse the coolant you drain from the system before removing the heater core , and the heater core is usually easy to get out). on the corolla i replace thermostat because the new one had malfunctioned resulting in it being partially open (a fail-open is better than a fail-closed themostat in my opinion, i'd rather be cold than be fixing a head gasket anyday) all the time and making it not retain heat resulting in blowing semi-warm air even tho my temp needle stayed up around 1/4 to even 1/2 except for serious highway speeds it'd drop to nothing or if nothing else seems to work you could put "restrictor" plates on the grill causeing less cold air to get under hood, the hicks here in nebraska usually use old cardboard beer cases on their trucks for that purpose. also just a thought, i had a car that had a failure somewhere in the ducts thru the fire wall and was pulling in cold air but that was a old car and fortunatley i've not had to get that far into the dash yet to find out if that can still apply these days with any cars. i noticed it because my old chevy used to blow air thru the ducts when it wasn't on and i don't mean the usual trace amounts i mean like it was set on medium. anyways, good luck and if all else fails just get a power converter and hook up a space heater to your passenger floorboard, it goes well with a boom box on the front seat. hahahaha, do what you gotta do!!!




seriously i'd advise against that set up considering it might fall over and start a fire, i had mine nail-gunned (carefully i swear) to the floor and was still constantly paranoid but hey it worked man.
