No ac in car – Nissan
If your Nissan minivan or SUV has no AC, you may be interested in this service bulletin (NTB09-028a). Nissan has issued this service bulletin to address a problem of low airflow on the following vehicles.
The problem occurs after driving for a long period with the AC on and blowing cold and the outside air is hot and humid. After a while you start to notice a drop in airflow. The drop in airflow continues until you have almost no air coming from the vents. This is a sign of evaporator freeze up caused by the evaporator temperature dropping to 32. At this point moisture in the air freezes on the evaporator coil.
In many cases, evaporator freeze-up can be a sign of low refrigerant charge. However, if the refrigerant charge in your vehicle is up to par, the problem may be a faulty intake air sensor. The bulletin recommends sensor replacement as the fix.
