Car AC not blowing cold air can be the result of the blocked condenser. The condenser job is to cool the refrigerant that gets hot during compressing. It is done by using the airflow from the front of the car when you drive on the road. The condenser can be blocked by dirt or debris from the way, and then it will not be able to cool the refrigerant and your cars ac system will not be able to walk properly and will not be able to give you cold air. As the condenser is in the front in most of the cars, so you can easily see if anything is blocking it and remove it.

#6 Broken Condenser

Sometimes, no debris is blocking the condenser; instead, it gets broken down due to some trash going into the condenser through the grill of the car and damage the part, causing failure. This type of condition can be detected by visual inspection, but their only remedy is by replacement of the condenser.

#7 Failure of Clutch Cycling Switch 

The clutch cycling switch can fail and cause your AC to not give cool air to you. In this situation, the air compressor’s electromagnetic clutch does not kick in, causing the refrigerant not to get pressurized and hence the system cannot work correctly. Replacing the compressor clutch is quite complicated, and it’s better to get it replaced by an experienced mechanic.
