Soon after the extremely cold change in the weather and my getting the windshield wiper transmission fixed on my 2003 Chevrolet Cavalier, my heat stopped working properly in my car. Before these two events the heat worked perfectly but I cant decide if it was the 15 below zero temperatures or the repair man who installed my windshield wiper transmission. We checked the fuses and it doesn't seem to be that and now I realize that when I drive really fast maybe 65-70 mph the heat comes out a little more but still not enough to keep you warm in this weather unless your constantly driving at those speeds for at least an hour. I was told that maybe it is the fan that is the problem but I'm just wondering how the fan could have suddenly stopped working? The heat didn't need to be on for 10 minutes before to get the entire car extremely hot and now its just dead. Please help me if you have any idea what is wrong. Thanks!
While this May be a coincidence, I would go back to the guy that worked on your car to have it checked.

It's very unlikely that your windshield wipers have anything to do with your heater. It doesn't sound like it's a fan because it's blowing air, it's just not warm. I would have your cooling system pressure check & possibly flush your heater core.

Unless the fan is stuck on all the time, that is most likely not the culprit for it taking so long to get heat. I would start with having the thermostat and water pump checked. Is the temp gauge on the dash in the normal range or is it running hotter than usual? Air in the cooling system will also result in poor heat, but you need to figure out where the air is coming into the system from.
