The use of AC dye leak detection is indicated when there is a problem with your vehicle’s air conditioning that is not easily attributed to a specific component. Many of the components of an AC system exhibit similar signs when they go bad.
For instance, you might notice that the AC compressor cycles on and off more rapidly than normal, a symptom of low refrigerant. The same issue, low refrigerant, could lead to warm air blowing from your vents rather than cool air. If the cause of low refrigerant is a leak, and the leak is not obvious (i.e. a bent or broken AC line), a technician would recommend this procedure as a means of diagnosis.
