TUNING THE AIR (CAR AIR CONDITIONING)

The basics of air conditioning system operation are reviewed. Instructions are provided for the service specialist on air conditioner tune-up. Information is given on how to charge the system when a low-charge condition is encountered. The three methods of leak testing in the case of complete or almost complete refrigerant discharge are described: propane torch, electronic leak detector, and sudsy mixture. Procedures are outlined for charging an empty system. Additional common problems and corrections are noted; they relate to insufficient cooling, no cooling, and noise in the system.
