My 2002 Oldsmoblie Aurora heat is not working. It blows cold air I changed the thermostat and it still blows cold air. What else could it be that I need to replace to fix the heat.

Could be your air blend door or the heater core is clogged-up

try pulling your hvac fuse inside car it may reset the blend door actuator pull for 60 seconds then reinstall. if not the blend door actuator may be bad or not getting power. if it's auto temp control then it may need scanning first.
