Replace fan realay or check wires. Mine stopped and i just replaced the relay.

Does any of you other climate control function work?

On thing it could be if you were not getting any airflow on your heat, cold, or AC is a vacuum line. There is a vacuum line as part of your climate control system and when mine went out I couldn't get any airflow.
