What determines AC system pressure?
Actual pressure will depend on the type refrigerant and the ambient temperature and does not show if the system is properly charged. At 85 degrees Fahrenheit, R134A shows a pressure of around 90 pounds per square inch. Much lower readings suggest the system is low on charge or contaminated with air.
What are common reasons my Nissan Frontier has air conditioning problems?
What are common reasons my Nissan Frontier has air conditioning problems? While there are a variety of reasons your Nissan Frontier air conditioning won’t work, the most common 3 are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.
Where does the pressure go in an air conditioner?
Your air conditioning system is split in half when it comes to pressure. Your air conditioning system holds a very high pressure between your AC compressor and condenser up expansion valve, and a relatively low pressure after the expansion valve and evaporator and back to the inlet of the compressor.
Can you add Freon to a frontier a / C system?
Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a refrigerant. The A/C system in your Frontier consists of a compressor that is belt-driven, an evaporator and freon. If there is a problem with your compressor or evaporator, adding freon will not restore cooling.
What kind of refrigerant does Nissan Frontier use?
Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a refrigerant. The A/C system in your Frontier consists of a compressor that is belt-driven, an evaporator and freon.
Why is the AC not engaging on my Nissan Frontier?
I recently moved back to Colorado from being in Vegas, so I’m thinking it didn’t like the trip. It is a 2007 frontier with 105k miles. I can cycle through all the speed settings on the blower just fine. AC light comes on but I can’t feel or hear the compressor engage. I checked the fuse under the hood and it was good (10 amp fuse).

How can I test the pressure in my air conditioner?
Connect both hoses to the proper ports and then loosen the other end of the hose at the gauges. The pressure in the system will push any air out of the hose. Quickly tighten the hose and then purge the other line. With quick-connects, the hoses will seal when removed and purging should not be needed again.
What are the symptoms of a bad AC pressure switch?
1. AC system cutting on and off rapidly 2. Unable to cool the car 3. Compressor not coming on Average rating from 53 customers who received a Heating AC Inspection. The AC pressure switch is a safety switch that is mounted on both the high and low sides of the air conditioning system.
