Why my chevy van only blows cold air in the front but not in the back?

If your Chevy van is only blowing cold air in the front but not in the back, it could be due to a malfunctioning rear climate control system or a clogged air duct. Another possibility is that the rear blower motor is faulty or not receiving power. Additionally, low refrigerant levels in the AC system can affect cooling performance in different areas of the vehicle. It’s best to have a professional diagnose and address the issue to ensure proper airflow and temperature control.
