Air Conditioning Not Cooling / Leak Test Using Fluorescent Dye
If you receive customer reports in the above model vehicles of the air conditioning not cooling, temperature fluctuations or noisy compressor
operation, the cause could be low refrigerant level. Refer to the applicable diagnostic tree in the Vehicle Heating, Ventilation, Air Conditioning
(HVAC) Manual found on STAR TekInfo --> EDAC --> Non EDAC Guides. The refrigeration system should be checked for leakage using
fluorescent dye as per the instructions supplied with the leak detection equipment. Please refer to the MBUSA Standard Service Equipment Program
(SSEP) catalog (1-888-458-4040).
Note:
In order to ensure compatibility with all components and materials in the AC system the only approved tracer dye additive to be used is

manufactured by Spectronics Corp. /Tracer Products. If other products are used, warranty submissions could be subject to debit.
