Do you know what may be the problem if the pressure in the low pressure part is too low and if the pressure in the high pressure system is too high? How does a variable displacement compressor operate?
Considering the demands of the modern vehicles market, the air-conditioning system in vehicles is not a luxury any more - it has instead become a bare necessity. There is practically not a single vehicle manufacturer who would allow himself the ‘’luxury’’ of launching a model on the market without an air-conditioning system.
Along with the demand to increase the air-conditioning device performances, manufacturers are also faced with the task of fulfilling the demand for lower fuel consumption. Modern air-conditioning systems in vehicles have therefore become very complex, although they all use the same physical operating principles. Complete acquaintance with these principles, as well as understanding of supporting systems managing the operation of the air-conditioning system, facilitate to a great extent proper diagnostics and defect repair.
Having this in mind, the capability of repairing the air-conditioning system is almost of the same priority as the repair of the power train!
