1991 Chevy Cavalier mileage: 116,000. I recently had problems with the heater in my car. I keep blowing fuses for my heater. We tried to replace the fan thinking that was the cause but no go. All the other fuses are working fine its just the heat. Can you think of any other problem? The only heat I am getting is when I get driving it automatically flows through the vent and baby it is cold outside in NY.

You need to perform a couple of tests. First, disconnect the power wire to the heater fan and turn on the controls for the heater to see if it blows a fuse. If it does, then you have problems in either the wiring or the control on the dash. Second, check the variable speed resister. It is usually located in the air duct close to the blower motor. It is possible that it has shorted out.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
