Automotive Air-conditioning and Climate Control Systems is a complete text and reference on the theoretical, practical and legislative aspects of vehicle climate control systems for automotive engineering students and service professionals. It provides the reader with a thorough up-to-date knowledge of current A/C systems, refrigerants and the new possible replacement systems like CO2, and includes unrivalled coverage of electronic and electrical control. Filling the gap in the automotive engineering and servicing market for students and those training on the job, this book will help both newcomers and those with more experience of air-conditioning systems maintenance engineering to keep up with the latest developments and legislation. Key Features.
Common Air Conditioning System Problems Only Hot air blows out the dash when I turn the Air Conditioning on. This is usually caused by a failing or failed Blend Door Actuator. The Actuator is usually located deep in the dash and attached to the hot/cold blend door. The most common fix is to simply have it replaced. Of course this is after you have made certain that the rest of your air conditioning system is functioning properly. Listen for the AC Compressor to click in and out and feel the accumulator for cold temperatures. These are signs of a normal operating AC System.
No air coming from air conditioning vents. Check the air conditioner fuse and replace as necessary. Air conditioner system discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
Air conditioner low pressure switch defective. Replace switch. Air conditioner fan resistor pack defective.
Replace resistor pack. Loose connection, broken wiring or defective air conditioner relay in air conditioning electrical circuit. Repair wiring or replace relay as necessary. Air Conditioner blows warm air. Air conditioner system is discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment.
Repair as necessary. Air conditioner compressor clutch not engaging. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary. Electronic Blend Door Actuator is not functioning which would only allow warm air to pass through vents. The AC lines going into the firewall would be cold if this is the case. Most common to replace actuator.

Water collects on the interior floor when the air conditioner is used. Air conditioner evaporator drain hose is blocked. Clear the drain hose where it exits the passenger compartment. Air conditioner evaporator drain hose is disconnected. Secure the drain hose to the evaporator drainage tray under the dashboard. Air conditioner has a moldy smell when used. The air conditioner evaporator drain hose is blocked or partially restricted, allowing condensation to build up around the evaporator and drainage tray.
All automotive air conditioning systems are (nearly) closed loops with a high-pressure side and low-pressure side. We'll start with the high-pressure side as it leads from the engine to the passenger compartment: Compressor: The compressor is a pump driven by a belt attached to the engine's.
