Car Air Conditioner Blower

The cool air felt from the dash vents is provided by the ac heater blower motor assembly.

Car air conditioner blower.

Classic auto air engineers have been using their multi faceted knowledge of classic car air conditioning to design the most high performance model specific a c kits available since 1977. Most car manufacturers use a series of resistors to make the heater blower motor run at different speeds. In addition you should also check the condenser fan s wiring and connection and its placement to see if it is positioned correctly. The first thing to check if your car air conditioner does not blow cold air is the condenser fan.

If your car s air conditioner isn t blowing cold air the first thing you should look for are signs of leaking or an a c compressor that does not engage. The resistor module is easy and inexpensive to replace. It s then typically installed in the ductwork near the car blower either under the dash or under the hood. The best setting for diagnosis is fresh air not recirculated with the air blowing out of the center vents in the dash and the ac turned on.

The ac evaporator acts like a huge ice cube. If you are feeling air and the blower motor is allowing the fans to produce air at all speeds you next want to feel the actual force of the air coming through. 1 blower fan problem. Carac not blowing air from vents because of the following.

A faulty automotive air conditioner can be one of the more difficult issues to diagnose and repair. Sometimes blower motors and or their resistors will fail and stop pushing both hot and cold air through the vents. A faulty blower fan can make the car ac stopped working suddenly. Turn the air conditioning on while the car is running.

Check the strength of airflow. And when one or more of these resistors burn out you re usually left with only one heater blower motor speed high. The air conditioner won t run properly unless your engine is running. The blower motor resistor or blower module gets hot as it powers the fan so often times they can burn out causing certain speeds of the fan in your car to stop working the fan can be stuck on one speed only work on high speed or not work on any settings.

The restoration trade and classic car enthusiasts widely consider classic auto air to have the highest quality products in the industry. If you do not feel any air or if you only feel air coming through the vents on certain settings the problem may lie with the ac s blower motor or the blower motor resistor. Start with the fan speed turned to its highest setting. If the fan is damaged and does not operate at full power it will not cool down the heat coming from the refrigerant.
