Poor Cooling

Poor cooling can be many things within your air conditioning system. Modern Auto Air diagnoses many air conditioning cooling problem by connecting a gauge set to the high and low pressure service fitting on your vehicle's system. Though poor cooling is often due to a low charge of refrigerant, it can also be caused by many other factors.
It could be a faulty low pressure cut out switch. This switch prevents the compressor from running if the refrigerant level is low. It can prevent the compressor from coming on.
It could be a faulty compressor clutch. The magnetic clutch on the compressor requires full battery voltage to engage. If the voltage is low, or the clutch coils have too much resistance, or the air gap in the clutch is too great, the clutch may not engage to drive the compressor. The best advice is to see a Modern Auto Air Technician and allow us to find what the problem is.
It could also be a bad temperature sensor an ambient air temperature sensor, interior air temperature sensor, evaporator temperature sensor, or sunload sensor. Again, the best advice is to see a Modern Auto Air Technician and allow us to find what the problem is.
