I can not get the air conditioning working properly; it blows very mild cold air, may be warm. Can you tell me where the actuators that open the mixed air between heat and air condition located at in the firewall of the car and how to access them? I checked air compressor, okay. Air cold. Heat working okay. I think that it is the climate control module defective. Before I replace it, I would like to check if I can manually open the actuator to cover the heat opening somewhat. Other Nissan models have the cable, mine is controlled by actuator, I think. Please let me know.
thanks

Hi,

There are two blend air door actuators on this vehicle. I attached two pics below. Pic 1 is the left side and pic 2 is the right side. The left actuator will be on the left side of the HVAC box and opposite for the right.

Are you certain that the compressor is working properly? It's odd that both actuators would go bad at the same time.

Here are a couple links you may find helpful:

Let me know if I can help.

Take care,
Joe
