Please check your Cooling Fluid level first! If the level it to low, there is not enough flow through the heater. If fluid level is OK, turn ignition on (without running the engine), turn the knob of your climate control from window defrost to air to feet. You must hear a noise behind the dashboard, because a little e-motor adjusts the airflow. Try the same with both temp. switch, from high to low. You can hear the flaps moving, if they do it. If you can't hear anything, your climate control is gone!
Check - self diagnostic: follow this procedure:
1) Turn on the vehicle.
2) Turn on the AC system to any setting.
3) Hold down the AC and the Recirculation buttons at the same time.
4) While still holding the AC and Recirculation button, turn the driver's side temperature control knob clockwise one click.
5) Release the AC and Re-Circulation buttons.
The code numbers will be displayed on the screen one at a time, if there are any code stored.
Write down the codes and come back or search the internet for more instructions.
