My car is not overheating, but the temp guage is at about 75%. I changed the thermostat and that didn't fix the problem. the fan is working. It's not leaking antifreeze. Also, the heater is not blowing hot or even warm air. I tried cleaning out the heater core with a can of compressed air, and that didn't fix it.
