If you notice any of the following conditions, have your vehicle checked right away:
Good Maintenance Practices - Section 2 - Header : Your A/C system requires proper air flow to operate effectively. Poor air flow across the condenser will impact system performance and can increase refrigerant system pressure.

Signs of Wear & Troubleshooting - Section 1 - Header : Your A/C system must be maintained with the correct level of refrigerant and appropriate pressure to work properly. An A/C system leak, which could result in incorrect fluid or pressure levels, could potentially harm or interfere with the performance of your A/C system. This would result in lack of or insufficient cooling performance. Common causes of A/C system leaks include:
Signs of Wear & Troubleshooting - Section 2 - Bullet 1 : Use a leak detection dye, such as ACDelco Fluorescent Tracer Dye. Be sure to use the dye that is specified for use with your systems oil and refrigerant type.
Signs of Wear & Troubleshooting - Section 2 - Bullet 2 : Look for dirt or containment build up around hose or line connections. This could be a sign that oil, which would attract and hold contaminants, is leaking out of the connection.
Signs of Wear & Troubleshooting - Section 2 - Header : To check your A/C system for leaks:
Signs of Wear & Troubleshooting - Section 3 - Bullet 1 : Set the climate control system to 'Heat' or 'Vent'
Signs of Wear & Troubleshooting - Section 3 - Bullet 2 : Set the blower fan on 'High' (roll down your windows if the interior becomes too warm)
Signs of Wear & Troubleshooting - Section 3 - Bullet 3 : Allow more distance between your vehicle and the one in front of you; this enables more air to enter the radiator easily
Signs of Wear & Troubleshooting - Section 3 - Header : If your engine begins overheating while driving in heavy traffic, the following steps can help alleviate the condition:
