Step 1
Inspect your drive belt for wear, stretch or cracks, on a regular basis. Damaged drive belts limit the function of the compressor. If the drive belt breaks, it stops the compressor completely. Without the compressor, the auto AC stops cooling and air circulation stops.
-
Step 2
Examine the air conditioning condenser periodically for damage or debris. The condenser, located in front of the radiator, circulates refrigerant as air flows across the fins, removing the heat from the refrigerant. When the fins are damaged or dirty airflow is restricted, the condenser cannot properly remove heat from the refrigerant. The AC will not cool as efficiently as possible.

Step 3
Check underneath your auto after you park. Is you see water dripping, the air conditioner's drain is working. If you find little or no water, make sure the drain isn't clogged. Wet carpeting is a sure sign of a clogged drain.

Step 4
Roll the windows down for the first few blocks before turning on the AC. If your AC has a re-circulation option, don't turn it on until the hot air has emptied from the vehicle.

Step 5
Reduce mold and mildew buildup in the evaporator box by turning off the AC circulation switch when you park your car. If you do not have a recirculation option, turn the AC away from "Max Air."
