First Ac guy says compresor is at 40% and to lower the AC vent temperature from 60 degrees fahrenheit a new compressor would be necessary. The car has a 10 p15 compressor. First AC guy says that a 10 pa 17 compressor would be best. There is a used japanese toyota denso 10 pa 17 compressor and also a new chinese compressor 10 pa 17. Which one is better?
