No Heat or AC.

My blower seems to work, but she never seems to get cold. I really cant test heat now but she didnt get warm the last time i needed her too.

It could be a few things such as the blend door, low freon level, bad compressor, faulty heater control valve, clogged heater core or a thermostat that's stuck in the open position.
