@hieuhn99 Most common causes of the condition you described would be a poor connection or a blower motor on its way out.

My blower fan works sometimes. Sometimes it will work fine till I hit a bump and sometimes it just stops working even when the car is in park. What might be the cause of this?

1999.5 nissan pathfinder blower motor fan works only on high speed. based on your video presentation it's the resistor the most likely problem. where can i find the resistor? could you please tell me the exact location and instructions on how to remove it. thanks a lot.

@clos039 The way you described your condition it sounds like maybe a blend door type problem that diverts air to the proper vents. When this malfunctions it can dump all the air behind the dash.

@renan111 A common cause of your complaint is when the condenser fan is not working properly. The condenser fan pulls air across the condenser when the vehicle is not moving and low speeds. At highway speeds you can sometimes have enough airflow without the fan working to blow cold air.

@lamont22222 Some models have a high blower relay that is used to bypass the resistor block and run the fan at full speed.
